Thyroid microcarcinoma is a malignant papillary tumour of the thyroid gland measuring < or = 1.0 cm in diameter. Prognosis and treatment are controversial. We report on a personal series of 28 cases of thyroid microcarcinoma observed over the period from 2000 to 2004. From 2000 to 2004, 199 consecutive total thyroidectomies were performed in patients with multinodular struma. The histological diagnosis was made by a pathologist according to the recommendations of the World Health Organization by means of sections of the thyroid gland of no more than 2 mm. At routine histological examination, 28 cases (14.07%) of "incidental" thyroid microcarcinoma were found. The mean tumour size was 4.10 mm (range: 0.12 to 10 mm). The tumours were multifocal in 2 patients, and none presented lymph node metastases. Thyoid microcarcinoma is a malignant tumour associated with a good prognosis. Multifocality should be the main factor considered in selecting the type of thyroid surgery. A total thyroidectomy may be regarded as sufficient treatment.

Nonmyeloablative allogeneic stem cell transplantation (NST) has been explored to overcome transplant-related mortality (TRM). From the review of 39 published reports, 50% of the 1484 treated patients had NSTs with truly nonmyeloablative conditioning (NMC) and 417 patients (29%) received an unrelated donor transplant (UDT). Median age was 49 years (range 17-59). A median dose of 4.74 x 10(6) CD34+ per kg (range 1.7-7.5) was administered. Hematological recovery was rapid with all the regimens used. Sustained engraftment was obtained in 1267/1355 assessable patients (94%, range 67-100%). Complete donor chimerism was observed in 707/948 assessable patients (75%, range 22-100%). Both were higher after reduced intensity conditioning (RIC) than after NMC regimens. Reject was more frequent after UDT and NMC regimens. Grades II-IV and III-IV acute graft versus host disease (GVHD) occurred in 580/1400 (41%; range 7-72%) and 188/1093 (17%; range 0-29%) assessable patients, respectively; grades II-IV and III-IV acute GVHD were more frequent after UDT and RIC regimens, respectively. Chronic GVHD occurred in 407/1046 assessable patients (39%; range 0-79%) and extensive chronic GVHD in 166/835 patients (20%; range 0-69%); they were more frequent after RIC regimens and less frequent after UDT. Transplant-related mortality (TRM) rate of 20.6%, without differences between RIC and NMC regimens, was observed; TRM was higher with UDTs. The most frequent causes of TRM were acute or chronic GVHD after RIC regimens and infections after NMC regimens and UDTs. Indolent lymphoid malignancies and some solid tumors appear sensitive to the graft versus malignancy (GVM) effect. NSTs could guarantee relatively low TRM and toxicity in patients not eligible for conventional allogeneic transplantation and could represent a platform for successive specific immunotherapy.

The aim of the study was to determine the safety and efficacy of the combination of fludarabine (FLU), cyclophosphamide (CY) and mitoxantrone (FLU/CY/MITO) in untreated follicular lymphomas (FL), Sixty patients with newly diagnosed stage II bulky to IV FL, median age 59 years (range 36-70), received FLU/CY/MITO regimen (FLU 25 mg/m2 days 1-3, CY 300 mg/m2 days 1-3, Mito 10 mg/m2 day 1). Patients received antibiotic oral prophylaxis during all treatments, and growth factors (G-CSF) when grade III granulocytopenia (WHO) occurred. The overall response rate was 87%: 46 patients achieved complete response (CR) (77%), 6 a partial response (10%) and 8 were non-responders. Fifty patients are surviving with a median observation time of 31 months. The 4-year estimated probability of overall survival and failure-free survival were 78.2% and 45% respectively. Thirty-five patients (58%) are still in CR. Sixty percent of patients experienced grade III-IV granulocytopenia. Two patients suffered grade III pulmonary infection and one grade III liver toxicity. In a subset of 46 patients, bcl-2 translocation was positive in bone marrow (BM) and/or peripheral blood (PB) of 36 patients. At the end of treatment, 25 of these patients had CR and 19 (76%) converted to polymerase chain reaction (PCR) negativity. FLU/CY/MITO regimen showed a high level of activity in follicular lymphoma. Toxicity, mainly hematological, was acceptable and the treatment was made feasible by the use of antibiotic prophylaxis and G-CSF. Significant non-hematological toxicities were seen, but no patients died. The conversion of bcl-2 from positive to negative by PCR in BM and/or PB suggests a possible role for this treatment in clearing minimal residual disease and improving patients' outcome.

The objective of this multicenter prospective study was to determine the clinical efficacy and toxicity of a polychemotherapeutic third generation regimen, VACOP-B, with or without radiotherapy as front-line therapy in aggressive localized non-Hodgkin's lymphoma. Ninety-three adult patients (47 males and 46 females, median age 45 years) with aggressive localized non-Hodgkin's lymphoma, 43 in stage I and 50 in stage II (non-bulky), were included in the study. Stage I patients received VACOP-B for 6 weeks plus involved field radiotherapy and stage II patients received 12 weeks VACOP-B plus involved field radiotherapy on residual masses. Eighty-six (92.5%) achieved complete remission and 4 (4.3%) partial remission. Three patients (3.2%) were primarily resistant. Ten-year probability of survival, progression-free survival and disease-free survival were 87.3, 79.9 and 83.9%, respectively. Eighty-four patients are surviving at a median observation time of 57 months (range: 6-126). Statistical analysis showed no difference between stages I and II in terms of response, ten-year probability of survival, progression-free survival or disease-free survival. Side effects and toxicity were negligible and were similar in the two patient groups. The results of this prospective study suggest that 6 weeks of VACOP-B treatment plus radiotherapy may be the therapy of choice in stage I aggressive non-Hodgkin's lymphoma. Twelve weeks of VACOP-B treatment with or without radiotherapy was shown to be effective and feasible for stage II. These observations need to be confirmed by a phase III study comparing first and third generation protocols in stage I-II aggressive non-Hodgkin's lymphoma.

Preoperative follicular lesion characterisation represents an unsolved diagnostic problem in thyroid nodular disease. Although fine-needle aspiration biopsy is the most reliable preoperative diagnostic procedure, it shows inherent limitations in differentiating adenoma from follicular carcinoma and, sometimes, follicular variants of papillary carcinoma. Galectin-3 cytoplasmic neoexpression has been proposed as a peculiar feature of thyroid malignant cells, easily detectable in cytological and histological samples. The aim of this study was to re-evaluate the galectin-3 expression in a large sample of thyroid lesions using an immunohistocytochemical biotin-free detection system and a specific anti-human-galectin-3 monoclonal antibody in order to avoid the interference of technical factors, a cause of conflicting results recently reported by some authors. We analysed galectin-3 expression of 39 follicular carcinomas, 26 papillary carcinomas, and 105 adenomas in both cell-block samples and their histological counterparts. All cell-block and histological papillary carcinoma samples showed high levels of galectin-3 immunoreactivity. Thirty-four follicular carcinomas were positive, whereas 5 were negative in cell-blocks but positive in their histological counterparts. Twelve out of 105 adenomas expressed galectin-3 in cell-blocks and histological samples. The diagnostic accuracy of preoperative galectin-3 evaluation in adenomas vs follicular carcinomas was 90.0%. Galectin-3 expression was also investigated in 22 minimally-invasive follicular carcinomas. All of them showed galectin-3 immunoreactivity in both cytological and histological specimens with the exception of two cases, where galectin-3 positivity was observed only in the surgical material. The routine correct use of galectin-3, by increasing the diagnostic accuracy of conventional cytology, improves the management of thyroid nodules and can lead to a sensitive reduction of useless thyroid surgeries.

Background: The role of routine frozen section (FS) in the surgical management of thyroid nodules remains uncertain. This study reviewed the role of FS in the presence of an adequate fine-needle aspiration biopsy (FNAB)., Methods: FNAB and FS were evaluated in 206 patients who had surgery for a thyroid nodule. Cytological specimens were classified as benign, malignant or suspicious. The FS diagnoses were benign, malignant or deferred., Results: A cytological diagnosis was obtained in 93 nodules; the remaining 113 were classified as suspicious, of which 21 were malignant on definitive examination. The overall accuracy of FNAB was 53 per cent. FS evaluation identified 165 lesions as benign; the diagnosis was deferred until definitive histological evaluation in only eight. The overall accuracy, therefore, was 96 per cent. Routine use of FS was cost-effective; lowering the number of reoperations led to an estimated saving of about 40 per cent., Conclusion: These data suggest that FS remains an important tool in the surgical management of thyroid nodules and can reduce the number of patients requiring reoperation.

From 1985 to 1998, at the Regional Cancer Center of Padua, patients with Hodgkin's disease (HD) routinely underwent a clinical staging procedure including lymphangiography and laparoscopy with multiple liver and spleen biopsies. Patients with IA and IIA nonbulky HD were treated with radiotherapy alone. The aim of this study is to analyze the efficacy of radiotherapy as radical treatment in this group of patients, and the role of lymphangiography and laparoscopy in the selection of patients with abdominal disease located to the spleen, liver, or the pelvic lymphatic chains. From January 1985 to January 1998, 94 previously untreated patients with biopsy-proven HD underwent clinical staging procedures consisting of history, physical examination, routine laboratory tests, chest radiography, total-body computed tomography scan, and bone marrow biopsy and were considered in stage I-IIA nonbulky. In addition, all patients underwent bipedal lymphangiography, which was positive in 12 (12.8%). Of the 82 patients with negative lymphangiography, 9 (11%) showed disease below the diaphragm at laparoscopy with multiple random spleen and liver biopsies. Of the remaining 73 patients, 32 were male and 41 were female with a median age of 29 years (range: 14-72 years).

This randomized phase II trial was performed to define the activity and toxicity of the combination of dacarbazine (DTIC), carmustine (BCNU), cisplatin (DDP) and tamoxifen (DBDT regimen) versus DTIC alone in patients with metastatic melanoma. Sixty patients with metastatic melanoma were randomly assigned to receive BCNU 150 mg/m2 intravenously (i.v.) on day 1, cisplatin 25 mg/m2 i.v. daily on days 1 to 3, DTIC 220 mg/m2 i.v. daily on days 1 to 3 and tamoxifen 160 mg orally daily for 7 days prior to chemotherapy (DBDT arm; arm A). Treatment cycles were repeated every 28 days, while BCNU was given every two cycles. The DTIC arm (arm B) patients received DTIC alone 1200 mg/m2 i.v. on day 1, repeated every 21 days. Patients were evaluated every two cycles; responding patients continued the treatment for a maximum of 12 cycles. The overall response rate was 26% in the DBDT arm and 5% in the DTIC arm. Complete responses were 2.5% for DBDT and 0% for DTIC. The median progression-free survival and the median survival were 4 and 9 months, respectively for DBDT, and 2 and 7 months for DTIC. DBDT was associated with significant haematological toxicity: 33% of the patients experienced a grade III or IV neutropenia and 28% a grade III or IV thrombocytopenia. In conclusion, the overall response rate obtained with DBDT was greater than that obtained with DTIC alone; however, this combination increases toxicity with limited impact on overall survival.

Using the ASI, a multi-dimensional survey instrument, data were collected on women in Florida's welfare program (WAGES). The women manifested serious problems in terms of physical and mental health, employment skills and childcare needs. Length of time on welfare was strongly associated with the severity of recipients' problems. Women with 2 + years on welfare were significantly more likely to have problems. However, substance use was lower than anticipated which may be because substance abusers are dropping out of welfare. This possibility raises concerns that, rather than going into the workfore, women may be returning to the streets. If so, instead of reducing the welfare costs, we are shifting those costs to local health, social service and criminal justice systems.

Background: Kaposi's sarcoma (KS) is the most common cancer seen in subjects with acquired immunodeficiency syndrome (AIDS). KS etiology and pathogenesis are still ill defined, and no definite improvement in survival has been obtained with current chemotherapeutic regimens. This open prospective study was aimed at evaluating the clinical response of AIDS-related KS to highly active antiretroviral therapy (HAART), a combination of protease and reverse transcriptase inhibitors, as well as the relationship between clinical response, human immunodeficiency virus type 1 (HIV-1) burden, and antibody titer against human herpesvirus 8 (HHV8) proteins., Patients and Methods: Fourteen KS patients were studied; 12 were in the poor-risk group. At given intervals, the patients underwent clinical examination, and their CD4(+) cell counts, plasma HIV-1 RNA levels, and antibody titers to lytic-phase ORF65 and latent-phase HHV8 proteins were determined., Results: When last seen, the overall clinical response rate was 86% (median follow-up, 22 months); 10 complete and two partial responses were achieved, and two patients showed disease progression. All patients with complete or partial response showed a consistent decrease in HIV-1 RNA levels, with a corresponding increase in CD4(+) cell counts; HIV-1 RNA levels in the two progressors remained persistently high, despite a change in HAART. HHV8 ORF65 antibody titers were generally higher in patients with extensive skin or mucosal/visceral involvement versus patients with limited disease; no differences in latent-phase HHV8 antibody titers were observed in relation to tumor burden., Conclusion: The findings indicate that antiretroviral therapy with protease inhibitors is effective for AIDS-related KS; the clinical response was correlated with a decrease in plasma HIV-1 RNA levels and an increase in CD4(+) lymphocytes, whereas antibody levels to the lytic-phase HHV8 protein were influenced by the extent of tumor involvement.

The clinical response of AIDS-related Kaposi's sarcoma (KS) to highly active antiretroviral therapy (HAART), a combination of human immunodeficiency virus type 1 (HIV-1) protease and reverse transcriptase inhibitors, was studied in 11 patients, all but one with progressive KS. CD4+ cell counts, plasma HIV-1 RNA levels, and antibody titres to lytic ORF65 and latency-associated human herpes virus type 8 (HHV-8) proteins were determined in sequential samples. Six complete and three partial clinical responses were achieved in a median time of 6 and 3 months, respectively, and confirmed after a median time of 16 months on HAART. 2 patients showed disease progression. A consistent decrease in HIV-1 RNA levels, paralleled by an increase in CD4+ cell counts, was observed in all patients who showed complete or partial clinical response; HIV-1 RNA levels remained persistently high in the two patients who progressed, despite a change in HAART. HHV-8 antibody titres were generally higher in patients with mucosal/visceral involvement compared with patients with limited disease; a decrease in ORF65 antibody titre was significantly associated with a clinical response. These results indicate that HAART is effective for AIDS-related KS; the clinical response correlates with a decrease in plasma HIV-1 RNA levels, an increase in CD4+ lymphocytes, and a decrease in antibodies to ORF65 HHV-8 protein.

Between 1989 and 1998 a total of 1250 thyroid nodes underwent Fine Needle Aspiration Biopsy (FNAB). Of these 150 went on to surgery with subsequent histological examination which proved positive for malignant neoplasm in 35 nodes. The remaining 115 nodes presented benign lesions. The cytological diagnoses were preventatively broken down into three groups: a) benign; b) malignant; c) suspected malignancy. Group a) included 53 nodes; histology confirmed the diagnosis of a benign lesion in 50 of these nodes (True Negatives), while 3 proved malignant (False Negatives). The cytological diagnosis of malignancy was reached in 24 nodes (group b) and subsequent histology confirmed the malignancy in 18 cases (True Positives) while the remaining 6 nodes tested negative for neoplasm (False Positives). Group c) included those thyroid nodes which cytology classified as follicular neoplasms and for which histology was required to reach a diagnosis of malignancy or benignity; for this reason these cases were not used in the evaluation of diagnostic reliability. Of these 15 (20.5%) proved malignant and 58 (79.5%) benign (44 follicular adenomas and 14 micro-macrofollicular struma nodes). On the basis of the above data, the diagnostic accuracy of FNAB is 88.3%, sensitivity 85.7% and specificity 89.3%. These findings are substantially in agreement with the international literature which considers cytological testing highly reliable. In analyzing the cases which were not confirmed by histology, it was interesting to note that among the 4 false positives--defined as the "presence of atypical cells in a lymphocyte infiltration context"--a full three were thyroadenitis nodes for which the presence of atypical cells is quite common. The three false negative nodes, on the other hand, included two cysts for which cytology did not reveal neoplastic cells. The present experience suggests the following: 1) FNAB is still the most reliable technique for the diagnosis of thyroid neoplasms; 2) the presence of atypical cells in thyroid node lesions is not always indication of a malignancy; 3) cysts must be subject to careful follow-up since they can mask a malignant neoplasm.

This study describes the therapeutic effect of carboplatin and gemcitabine in combination for malignant pleural mesothelioma (MPM). Twenty patients (14 males and 6 females) with a median age of 53 years entered the study. These patients had histologically proven MPM with no previous chemo- and/or radiotherapy and malignancies. A total of 91 cycles of treatment were administered to 20 patients with a median of 4 cycles per patient. A partial response was observed in 4 out of 20 patients (20%, 95% confidence interval: 6-43%). No complete responses were observed. Only 5 patients (25%) had progressive disease. The response duration ranged form 4+ and 21 months.

Aims and Background: The stomach is the most common site of primary extranodal non-Hodgkin's lymphoma (NHL) and no agreement has been reached so far on the best therapeutic approach. The main objects of this study were to report the long-term results and to evaluate the importance of some possible prognostic factors in a large series of patients. NHL was considered primary gastric if the main symptoms at presentation were those of gastric disease., Methods and Study Design: We analyzed 252 consecutive patients treated between 1980 and 1993 in five hospitals in north-east Italy. According to the Working Formulation, 98 patients had low grade lymphoma, 59 intermediate grade (D to F), 81 G or high grade and 14 were not classified. The patients were divided into two groups: one including patients with limited disease (localized to the stomach or perigastric lymph nodes: 165 patients) and one including those with advanced disease (87 patients). The treatment consisted of surgery, chemotherapy, radiotherapy or combinations of these. Sixteen patients received only supportive therapy., Results: The five-year overall survival was 65.4%: 80.3% for patients with limited disease and 36.7% for those with advanced disease (P < 0.0001). Among the limited disease patients the five-year survival was 84.4% for those treated with gastrectomy alone and 88.7% for those who received also adjuvant chemotherapy (P = 0.11). However, while chemotherapy did not improve survival in low grade NHL, it seemed to produce a better survival in the intermediate and high grade groups (P = 0.06). Twelve patients were treated with primary chemotherapy and the five-year survival was 71.2%. In multivariate regression analysis the most important variable for overall survival was surgery for the whole group of 252 patients (P < 0.0001), while it was age for the group with limited disease (P = 0.0008)., Conclusions: Surgery alone can be curative for most patients with gastric lymphoma limited to the stomach or to the perigastric lymph nodes; surgery followed by chemotherapy seems to produce better results than surgery alone in intermediate and high grade lymphomas. Also a non-surgical approach with first-line chemotherapy is associated with a high rate of complete remissions and five-year survival. In advanced disease the five-year survival is similar to that of nodal NHL.

Aims and Background: Kaposi's sarcoma (KS) is the most common neoplastic complication of HIV infection and AIDS. Multiple cytotoxic chemotherapy regimens have been used with various response rates. We have evaluated the efficacy and toxicity of low-dose chemotherapy in patients with poor-prognosis AIDS-related KS and the role of interferon alpha (IFN-alpha) in complete responders., Methods: Twenty-five previously untreated patients with advanced KS received bleomycin (BL) 10 mg/m2 and vinblastine (VB) 6 mg/m2 on days 1 and 15 every two weeks. After six cycles, patients in complete remission received IFN-alpha (3 million U s.c. 3 times/week) combined with antiretroviral therapy. All patients were evaluated for toxicity using the World Health Organization (WHO) toxicity schedule. Both Eastern Cooperative Oncology Group (ECOG) and AIDS Clinical Trials Group (ACTG) response criteria were used to evaluate response and survival., Results: The overall response rate was 84% (95% confidence interval, 51-117%) with six complete remissions (24%) and 15 partial remissions (60%) by ECOG criteria, and 92% (95% confidence interval: 58-128%) with 17 partial remissions (68%) by ACTG criteria. The median duration of response on IFN-alpha treatment was 4.5 months (range, 2-10). The overall median survival duration for all 25 patients was 9 months (range 2-39). Grade 3-4 anemia was observed in five patients and grade 3-4 neutropenia in two patients. No other clinically significant (> or = grade 3) toxicities were observed., Conclusions: Combination of BL and VB is effective and well tolerated, even if new therapeutic options are developing. This disease remains a challenging problem, so larger studies using the combination of chemotherapy and/or IFN-alpha with antiretroviral treatment are warranted.

This report describes the development and validation of an instrument to assess the attributions human immunodeficiency virus (HIV)-infected persons who are currently taking antiretrovirals make about the effects of these medications. The specific limitations in functioning that the subjects attributed to the effects of medication were assessed. The scores on a ten-item instrument were found to have high internal consistency reliability and to be related to beliefs about the benefits and barriers to taking antiretrovirals. The attribution that the use of antiretrovirals had contributed to an increase in depressive symptoms was related to reports of having temporarily discontinued use of antiretrovirals during the preceding month. The summated score on the Medication Attribution Scale (MAS) and other subscale scores were not found to predict self-reported intentional alterations of treatment regimens. Multiple regression analyses indicated that negative attributions about the effects of medications contributed to the amount of variance in quality of life explained over and above that explained by perceived health status and level of symptomology.

This study examines variables related to alteration of antiretroviral medication regimens by HIV infected persons, independent of medical advice. Perceived severity, susceptibility, benefits/barriers, cues to action, and locus of control were included in the analyses. Of 99 subjects, 37 reported discontinuing antiretrovirals on their own initiative and 36 subjects ('fiddlers') reported recent alterations in their medication regimens. Subjects who reported greater perceived barriers and pessimism and less faith in the ability of antiretrovirals to protect them from AIDS related illness were more likely to discontinue drug therapy. Fiddlers were more pessimistic and perceived more barriers to drug therapy than compliers, who believed more in the benefits of antiretrovirals. Fiddlers were significantly more internally oriented than were discontinuers. Compliers were the most optimistic about the effect of antiretrovirals. Even though compliers were more symptomatic than discontinuers, they reported their health status to be better than did discontinuers.

Background: In patients with advanced Hodgkin's disease (HD), the alternation of MOPP with ABVD or hybrid MOPP/ABVD are associated with a high CR rate and a high probability of 5-year survival. However, even after effective chemotherapy the risk of nodal relapse is not negligible, and not only in initial bulky site(s) of disease. For this reason, in an attempt to prevent relapses after combination chemotherapy alone, we performed a prospective study to evaluate the efficacy and toxic effects of 6 courses of hybrid MOPP/ABVD followed by radiotherapy (RT) in stages II A bulky, II B, III and also in stage IV with bulky disease of residual after chemotherapy., Patients and Methods: From January 1985 to August 1993, 133 patients with HD (128 newly diagnosed, stage II A bulky-IV, 5 in first relapse after RT) were treated according to the following program: 6 courses of the hybrid MOPP/ABVD regimen followed by RT (STNI + spleen in stages II A, II B, III without pelvic lymph node involvement, TNI + spleen in stage III with pelvic lymph node involvement, involved field in stage IV with bulky disease or residual after chemotherapy). The total dose of RT was 4000 cGy to the sites of bulky or residual disease and 2000 cGy to the other sites., Results: After hybrid MOPP/ABVD, 107 of 130 (82.3%) fully evaluable patients were classified as in CR or CR(U). After completion of RT, 108 patients were in CR and 3 were in PR, for an overall response rate of 85%. With a median follow-up duration of 45 months, the actuarial 5-year survival is 76% and the progression-free survival 68.6%. So far, only 14 patients have relapsed (6 within the irradiation field) and the 5-year relapse-free survival is 82.5%., Conclusion: Six courses of hybrid MOPP/ABVD followed by RT in stages II A bulky, II B, III and in stage IV with bulky disease or residual after chemotherapy produced a high CR rate with low risk of relapse. However, a longer follow-up is necessary to evaluate the late effects of combined therapy.

Mitoxantrone has shown moderate activity in advanced epithelial ovarian cancer following intermittent i.v. administration. Experiments and clinical data suggest that long-term continuous drug infusion may achieve a better therapeutic result with less toxicity. This hypothesis was tested in patients with advanced ovarian cancer who had been pretreated with other agents. Mitoxantrone was infused continuously in 21-day courses beginning every 6 weeks. If severe toxicity did not occur, the infusion rate was increased by 0.1-0.2 mg/m2 per day. The mitoxantrone solution proved to be stable over the 21-day infusion period. For ethical reasons an optimal two-stage design was employed. The trial was interrupted at the end of the first recruitment stage because the target of 3 responses out of 13 patients had not been achieved (only 1 patient had a partial response). Hematologic toxicity was observed in 11 patients, and 2 of them had a catheter occlusion. In conclusion, we found that 21-day of infusion of mitoxantrone apparently has no clinical benefit as compared with bolus administration in patients with advanced ovarian cancer.

We describe a 41-year-old woman, in whom antiphospholipid antibody syndrome (APS) occurred at presentation, before the detection of an ovarian endometrial adenocarcinoma. This syndrome was characterized by widespread and worsening thromboembolism and it did not respond to conventional anticoagulant treatment. The paraneoplastic nature of this APS was strongly suggested by the disappearance of both thromboembolism and antiphospholipid antibodies only after surgical removal of the cancer.

The contribution of medications to stress among family caregivers and the need of caregivers for pharmaceutical care services were studied. Persons in northern Florida who were caring for a family member at home who was at least 55 years of age and routinely took at least one medication were asked if they would consent to an interview. The interview was designed to elicit information about the characteristics of the caregiver and care recipient, stressors stemming directly from the medications (such as adverse effects) and arising from problems in managing the drug regimen (such as compliance), the mediators of medication-related stress (such as services received from the pharmacist), and the outcomes of stress (such as the caregiver's satisfaction with services). A total of 31 caregivers agreed to be interviewed. The mean +/- S.D. ages of caregivers and recipients were 63 +/- 13 and 80 +/- 10 years, respectively. Medication-related tasks accounted for only 7.7% of the total caregiving time. However, medications contributed substantially to caregivers' stress, with 10 caregivers (32%) reporting problems directly related to medications and 6 (19%) and 16 (52%) reporting problems in managing the drug regimen currently or within the past year, respectively. Twenty-two (71%) used the same pharmacy regularly, and 18 (58%) saw the same pharmacist regularly. Twenty-five caregivers talked with others about medication concerns. Of these, 18 (72%) discussed their charge's drug therapy with a physician but only 10 (40%) with a pharmacist.(ABSTRACT TRUNCATED AT 250 WORDS)

Background: Patients with Hodgkin's disease whose initial complete remissions (CR) after primary chemotherapy were longer than 1 year are thought to have better prognoses than patients whose initial remissions were shorter than 1 year. However, only a few studies have analyzed the long-term survival in addition to the results of retreatment in patients relapsing after CR lasting more than 1 year., Patients and Methods: We analyzed the data of 40 patients with Hodgkin's disease who were treated in a single institution and whose CR were > 1 year after primary chemotherapy. Therapy at relapse was not standardized: of 36 patients evaluable for response, 29 received second-line chemotherapy and 7 received radiotherapy alone., Results: Sixty-five percent of the patients obtained CR (median duration: 21 months). Sixty-eight percent of the complete responders relapsed again; however, long-lasting third and fourth remissions were observed. All of the 7 patients whose retreatment consisted of radiotherapy alone obtained CR, but only 1 is in continuous CR. The presence of nodular sclerosing histologic subtype, the absence of extranodal involvement and the use of hybrid MOPP/ABVD or ABVD alone as salvage treatment are independently associated with a higher CR rate and a higher probability of 5-year survival. The 5-year survival for all 40 patients is 49%. For the patients obtaining CR, the 5-year survival and the 5-year relapse-free survival are 76% and 25%, respectively. However, the survival curve continues to fall in the succeeding years because of third and fourth relapses and the occurrence of secondary acute leukemia and non-Hodgkin's lymphoma., Conclusions: A high percentage of patients relapsing more than 12 months after primary chemotherapy can obtain second CR. Even if most of our patients eventually relapse, third and fourth CRs are not uncommon. However, the long-term survival is low and it is further diminished by secondary leukemia and non-Hodgkin's lymphoma.

Aims and Background: Patients treated for Hodgkin's disease with chemotherapy or with the association of chemotherapy and radiotherapy have an increased risk of secondary leukemia. The aim of this study was to evaluate the leukemogenic risk due to these treatment modalities., Methods: We performed a case-control study on a population of 1410 patients treated for Hodgkin's disease from 1970 to 1990 in our Institute. Among these patients, we identified 25 cases of secondary leukemia and 3 cases of myelodysplasia, all occurring more than one year after the diagnosis of Hodgkin's disease. Three cases occurred among the patients treated with radiotherapy alone. When we analyzed the risk in relation to the type of treatment (radiotherapy, chemotherapy, or both), the comparisons were relative to patients treated with radiotherapy alone., Results: We found that chemotherapy alone is associated with a fivefold increased risk (odds ratio = 5.4) compared with radiotherapy alone. When both treatments are used, the risk is not further increased (odds ratio = 4.4). Patients receiving more than 6 courses of chemotherapy have an excess risk (relative risk = 2.5) compared with those treated with 6 courses or less. No increased risk was observed after splenectomy., Conclusions: This study confirms an increased incidence of secondary leukemia occurring in patients treated for Hodgkin's disease. The increased risk seems to be correlated with the number of courses of alkylating agent therapy, whereas it is unaffected by the addition of radiotherapy.

From January 1988 to December 1991, 55 elderly patients (14 pretreated and 41 previously untreated) with non-Hodgkin's lymphoma (NHL) entered a prospective study to evaluate the feasibility of a combination of mitoxantrone (7-9 mg/m2), VP 16-213 (150 mg, 2-hour infusion on day 1, and 200 mg per os on days 3 and 5) and low-dose prednisone (25 mg days 1-5) (MVP regimen), recycling every 21-28 days. The median age was 75 (range 64-93). All but 4 pretreated patients had intermediate- or high-grade lymphomas. Complete remissions were obtained in 22 of 40 (55%) evaluable previously untreated patients, and partial remissions in 10 (2 of these obtained complete remissions after radiotherapy), for an overall response rate of 80%. The median duration of response was 12 months. At 24 months the overall survival was 52% and the relapse-free survival was 31%. Of 14 pretreated patients complete remissions were obtained in 4 (29%) and partial remissions in 3. Granulocytopenia and fever were the most important side effects; two patients contracted bronchopneumonia and one of them died. Other toxicities were mild. We conclude that this combination chemotherapy is effective as first-line and salvage treatment in elderly patients with intermediate- and high-grade NHL, and that it is feasible on an outpatient basis, with manageable toxicity.

A very simple, low dose, orally administered regime (10 to 15 mg of fluoximesterone + 6 mg of deflazacort daily for periods of 1 to several months) resulting in mild-acceptable toxicity (essentially some weight gain) determined subjective improvement in 2/3 of 34 evaluable patients (out of 36 treated) and an objective measurable tumor reduction in 1/3, although most patients had been previously treated with chemotherapy and hormone treatment and proved primarily or secondarily refractory. The receptor status at the beginning of fluoximesterone+deflazacort treatment was not known, except in one negative-receptor patient, who responded to the combination after becoming resistant to tamoxifen (see photo). In some patients the condition of hormone refractoriness would suggest a no-treatment policy, but a trial with this regime is always convenient as it may improve both duration and quality of life.

A total of 21 untreated patients (5 males, 16 females; median age, 55 years; range, 28-72) with advanced measurable colorectal carcinoma were treated with an association of 5-fluorouracil (1000 mg/weekly) and alpha-2 interferon (three times a week s.c.: 6 x 10(6) U in the 1st month, 9 x 10(6) U in the 2nd month, 12 x 10(6) U in the 3rd month and then 18 x 10(6) U) until maximum response or progression of disease. Sites of disease involved liver in 10 patients, lung in 6, supraclavicular lymph nodes in 3, skin in 1, abdomen in 4, and vagina in 1 patient. Nine responses (42.8%) were documented (4 complete and 5 partial) with metastases confined to the liver, lung, nodes and skin. Median duration of response was 11 months (range, 4-17+) and median survival was 10 months (range, 2-17+). Side effects (fever, flu-like syndrome and leukopenia) required a dose reduction of 5-fluorouracil in 8 patients and interferon in 2 patients.

Thirty-two patients with stage III or IV invasive thymoma (14 women and 18 men; median age, 40 years) were treated at the Padua Medical Oncology Department from 1977 to 1988. All patients received the following chemotherapy in 4-day courses: 50 mg/m2 of cisplatin intravenously (IV) and 40 mg/m2 of doxorubicin IV on day 1; 0.6 mg/m2 of vincristine IV on day 3; and 700 mg/m2 of cyclophosphamide IV on day 4 (ADOC). The courses were repeated every 3 weeks, and toxic effects were tolerable. The radiologically defined overall clinical response rate (complete plus partial response) was 91% with 47% clinical complete remissions; median time to progression was 11 months (range, 0 to 96) and the median estimated (Kaplan-Meier) progression-free interval was 22 months. Five of the 15 clinical complete remissions were pathologically confirmed at thoracotomy. We believe the ADOC regimen qualifies for adjuvant and preoperative treatment of invasive thymoma due to the high complete response and overall response rates.

Clinical response to high-dose medroxyprogesterone (MPA), administered following three different routes of administration (i.m., p.o. + i.m., p.o.) and monitoring drug plasma levels, was evaluated in pretreated advanced breast cancer patients. Fifty-eight of 68 eligible patients were considered evaluable for response. Age ranged between 36 years and 82 years. Fifty-six of 58 evaluable patients were postmenopausal. An overall remission rate of 48% was achieved with i.m. MPA, 50% with combined (i.m. + p.o.) modalities; only a 19% remission rate was recorded in the p.o. group. Response rate and MPA plasma concentrations were correlated, and a drug level of 80 ng/ml, by means of a GLC method, seems to identify a subset of patients with high probability of response. Only mild toxic effects were recorded.

Data are presented on 15 cases of invasive tracheobronchial tumours subjected to cryotherapy in 1984-85. The technique is indicated in patients who cannot be given surgical or radiation treatment and in cases of asphyxial syndrome requiring faster deobstruction than is obtainable with radiation treatment.

The activity of the association of cis-platinum with Adriamycin and cyclophosphamide (CAP), as "rescue" chemotherapy for the treatment of refractory and relapsing advanced breast cancer, is presented. Of 42 evaluable patients, previously treated with chemotherapy +/- hormone therapy, 4 (9.5%) achieved a complete response, 15 (35%) had a partial response (CR + PR = 45%). Major toxicity observed was: nausea and vomiting in 95% of patients and leukopenia in 60%.
