Introduction: The objective of this study was a multicentric evaluation of professional practices, analyzing the irradiation technique itself and its impact on survival and recurrence sites, in primary central nervous system lymphomas (PCNSLs)., Methods: We retrospectively analyzed the technical and clinical records of 79 PCNSL patients included in the database of the national expert network for oculocerebral lymphoma ('LOC') who were treated with brain radiotherapy as first-line treatment for newly diagnosed primary central nervous system lymphoma between 2011 and 2018., Results: The number of patients treated with brain radiotherapy gradually decreased over time. The heterogeneity of radiotherapy prescriptions was significant, and 55% of them did not comply with published recommendations in terms of irradiation dose and/or volume. The proportion of complete responders to induction chemotherapy treated with reduced-dose radiotherapy increased over time. Partial brain radiotherapy was associated with significantly lower overall survival in univariate analysis. In partial responders to induction chemotherapy, increasing the total dose to the brain >30 Gy and adding a boost to the WBRT induced a trend toward improved progression-free and overall survival. Five recurrences (13%) occurred exclusively in the eyes, all in patients whose eyes had been excluded from the irradiation target volume and including 2 patients without ocular involvement at diagnosis., Conclusion: The visibility of recommendations for prescribing brain radiotherapy for the treatment of newly diagnosed primary central nervous system lymphoma needs to be improved to harmonize practices and improve their quality. We propose an update of the recommendations.

Due to the heterogeneity of tumour mass segmentation methods and lack of consensus, our study evaluated the prognostic value of pretherapeutic positron emission tomography with fluorodeoxyglucose (FDG-PET) metabolic parameters using different segmentation methods in patients with localized anal squamous cell carcinoma (SCC). Eighty-one patients with FDG-PET before radiochemotherapy were retrospectively analyzed. Semiquantitative data were measured with three fixed thresholds (35%, 41% and 50% of Maximum Standardized Uptake Value (SUVmax)) and four segmentation methods based on iterative approaches (Black, Adaptive, Nestle and Fitting). Metabolic volumes of primary anal tumour (P-MTV) and total tumour load (T-MTV: P-MTV+ lymph node MTV) were calculated. The primary endpoint was event-free survival (EFS). Seven multivariate models were created to compare FDG-PET tumour volumes prognostic impact. For all segmentation thresholds, PET metabolic volume parameters were independent prognostic factor and T-MTV variable was consistently better associated with EFS than P-MTV. Patient's sex was an independent variable and significantly correlated with EFS. With fixed threshold segmentation methods, 35% of SUVmax threshold seemed better correlated with EFS and the best cut-off for discrimination between a low and high risk of event occurrence was 40 cm 3 . Determination of T-MTV by FDG-PET using fixed threshold segmentation is useful for predicting EFS for primary anal SCC. If these data are confirmed in larger studies, FDG-PET could contribute to individualized patient therapies.

Introduction: Hypofractionated stereotactic radiation therapy (HSRT) for vertebral metastases gives good results in terms of local control but increases the risk of fracture in the treated volume. Preclinical and clinical studies have shown that zoledronate not only reduces the risk of fracture and stimulates osteoclastic remodeling but also increases the immune response and radiosensitivity. This study aimed to evaluate the tolerability and effectiveness of zoledronate in association with radiation therapy., Patients and Methods: We conducted a multicenter phase 1 study that combined HSRT (3 × 9 Gy) and zoledronate in patients with vertebral metastasis (NCT01219790). The principal objective was the absence of spinal cord adverse reactions at 1 year. The secondary objectives were acute tolerability, the presentation of a bone event, local tumor control, pain control, progression-free survival, and overall survival., Results: Thirty patients (25 male, 5 female), median age 66 years, who were followed up for a median period of 19.2 months, received treatment for 49 vertebral metastases. A grade 3 acute mucosal adverse event occurred in 1 patient during the treatment and in 2 more at 1 month. No late neurologic adverse events were reported at 1 year. The mean pain scores diminished significantly at 1 month (1.35; P=.0125) and 3 months (0.77; P<.0001) compared with pain scores at study entry (2.49). Vertebral collapse in the irradiated zone occurred in 1 (2%) treated vertebra. Control of local disease was achieved in 94% of irradiated patients (3 local recurrences)., Conclusion: The combination of zoledronate and HSRT in the treatment of vertebral metastasis is well tolerated and seems to reduce the rate of vertebral collapse, effectively relieve pain, and achieve good local tumor control with no late neurologic adverse effects., (Copyright © 2016.

Background and Objectives: Definitive chemoradiotherapy (CRT) is considered curative intent treatment for locally advanced esophageal squamous cell carcinoma. Data concerning the usefulness of definitive CRT in patients with esophageal adenocarcinoma (ADC) are lacking. The aim of the study was to compare the results of definitive CRT versus surgery in patients with an ADC., Methods: All consecutive patients with a non-metastatic ADC treated between 1994 and 2008 were retrospectively assessed. Patients were divided into two groups: surgery group (±pre-operative treatment) versus definitive CRT group., Results: In surgery and definitive CRT groups, 67 and 79 patients were evaluated, respectively. A complete resection was achieved in 92.5% of patients in surgery group and a clinical complete response was observed in 49.4% of patients in definitive CRT group. Overall survival was 36.2 ± 2.0 months in surgery group versus 16.5 ± 0.8 months in definitive CRT group (P = 0.02). The predictive factors of survival were age (P < 0.01), stage (P = 0.04), WHO performance status (P < 0.01), initial weight loss (P < 0.01), and the treatment group (P < 0.01)., Conclusions: The results of the study do not support definitive CRT as an alternative to surgery in esophageal ADC treatment. Definitive CRT should be reserved for patients with a major operative risk., (Copyright © 2011 Wiley Periodicals, Inc.)

Background: The risks of chemoradiotherapy in elderly patients with rectal cancer have not yet been well-characterised., Methods: We retrospectively reviewed the charts of patients with rectal cancer over 70 years old who were treated with chemoradiotherapy in two French university hospitals., Results: A total of 125 patients were evaluated. Mean age was 75.1 ± 4.1 years and ranged from 70 to 90 years. Adverse effects ≥ grade 2 were observed in 32% of the patients and adverse effects ≥ grade 3 in 15%. Dose reduction for toxicity was performed in 18% of the patients and chemoradiotherapy discontinuation was necessary in 9%. Postoperative morbidity was 16% with two treatment-related deaths. Two-year survival rate was 84%. No variables had any influence on treatment-related adverse events., Conclusions: In selected elderly patients, chemoradiotherapy is well-tolerated, without any significant increase in adverse events, and the results are similar to those recorded in younger patients., (Copyright © 2011 Editrice Gastroenterologica Italiana S.r.l.

Objective: To evaluate the clinical course and pathological characteristics of basaloid head and neck squamous cell carcinoma., Method: Retrospective study of 18 cases of basaloid head and neck squamous cell carcinoma. Epidemiological, clinical and histological data were analysed and the Kaplan-Meier test used to estimate survival rates., Results: The majority of lesions were at an advanced stage. These lesions were primarily localised in the larynx, hypopharynx and oropharynx. Routine pre-therapeutic assessment of squamous cell carcinoma was performed. Pathological diagnosis was difficult, although immunostaining was extremely useful. Positive staining for KL1, MNF 116 and 34βE12 and negative immunostaining for chromogranin and synaptophysin were also important factors in obtaining a definitive diagnosis. In the majority of cases, treatment involved surgery and radiotherapy. The five-year survival rate was 5 per cent., Conclusion: Basaloid squamous cell carcinoma is an uncommon head and neck lesion, with a challenging histological diagnosis. These lesions must be carefully monitored due to their aggressive course, and require multimodality treatment.

Background: Only limited data has been reported so far regarding oesophageal cancer (EC) in elderly patients. The aim of the study is to identify the baseline parameters that influenced therapeutic decision., Methods: All consecutive patients 70 years or older being treated for EC were retrospectively analyzed. Patients without visceral metastasis were divided into two groups: treatment with curative intent (chemoradiotherapy, surgery, radiotherapy, mucosectomy or photodynamic therapy) or best supportive care (BSC). Patients with metastasis were divided into two groups: palliative treatment (chemotherapy, chemoradiotherapy or radiotherapy) or BSC., Results: Two hundred and eighty-two patients were studied. Mean age was 76.5 ± 5.5 years and 22.4% of patients had visceral metastasis. In patients without visceral metastasis (n = 220) the majority had treatment with curative intent (n = 151) whereas in patients with metastasis (n = 62) the majority had BSC (n = 32). Severe adverse events (≥ grade 3) were observed in only 17% of the patients. Patients without specific carcinologic treatment were older, had more weight loss, worse WHO performance status and Charlson score in multivariate analysis., Discussion: Our results suggest that elderly patients with an EC could benefit from cancer treatment without major toxicities. Weight loss, WHO performance status and the Charlson score could be used to select the appropriate treatment in an elderly patient.

Objective: The optimal treatment strategy for rectal cancer (RC) with synchronous metastases remains an issue of debate. The aim of this study was to evaluate the impact of surgery and radiation on the control of pelvic symptoms in this setting., Methods: Consecutive patients with RC and synchronous metastases were retrospectively assessed and divided into four treatment groups: surgical resection of rectal tumor (S); radiotherapy with/without chemotherapy followed by surgery (CRTS); chemoradiotherapy (CRT); and chemotherapy only (CT). Each group was evaluated in terms of duration of pelvic symptom-free periods (relative to overall survival)., Results: A total of 96 patients were evaluated: S: n=30; CRTS: n=21; CRT: n=27; and CT: n=18. After treatment, pelvic symptoms persisted in 14.7% patients (S=0%, CRTS=7.1%, CRT=31.8%, CT=25%; P=0.01). The relative pelvic symptom-free periods were 93.0% in the S group, 83.1% in the CRTS group, 53.0% in the CRT group and 53.2% in the CT group (P<0.01). On multivariate analysis, only surgical treatment correlated with a significant relative pelvic symptom-free period (P<0.01), with an adjusted hazards ratio of 2.80 [95% CI: 1.79-4.39]., Conclusion: Our results suggest that rectal resection was the most effective therapeutic procedure in selected patients with RC and synchronous metastases, offering the patients the longest pelvic symptom-free periods.

We report a case of anal cancer with iris metastasis and summarize the iris metastasis literature. A 69 years old woman with a history of anal cancer presented with a visual field loss. Slit lamp examination showed a pink ovular mass on the iris of the left eye which was typical of iris metastasis. Because of worse prognosis of metastatic cancer and any ocular complications, the patient was treated by radiotherapy which allowed a clinical improvement. A review of medical records was performed to assess the clinical presentation, diagnosis and treatment. Anal carcinoma can metastasize to the iris. Radiotherapy allows a good local control of tumour but the prognosis depends on systemic disease which is generally bad.

Patients with gastric adenocarcinoma frequently develop hepatic metastases or peritoneal carcinosis but involvement of the skeletal muscle is extremely rare. We report the case of a 71-year-old man with a painful soft tissue mass in the right shoulder. Two years previously, the patient had been treated for a locally advanced gastric carcinoma (surgery plus chemoradiotherapy). Surgical exploration with biopsy showed skeletal muscle metastasis from the gastric adenocarcinoma in the deltoid muscle. Chemoradiotherapy resulted in complete regression of symptoms from the metastatic lesion. The patient is alive and free of recurrence in the deltoid muscle after a follow-up of 13 months. Based on this case study, the difficulty of diagnosing skeletal muscle metastases, the prognosis and treatment options are discussed.

Little is known about chemoradiotherapy (CRT) in elderly patients with a locally advanced oesophageal cancer (OC). The aim of our study was to evaluate the tolerance and the outcome of elderly patients older than 70 years treated with CRT for a non-metastatic OC. Chemoradiotherapy was based on radiotherapy combined with a cisplatin-based chemotherapy. Clinical complete response (CCR) to CRT was evaluated on upper digestive endoscopy and computed tomography scan 6-8 weeks after CRT completion. One hundred and nine consecutive patients were included. A CCR was observed in 63 patients (57.8%) and 2-year survival was 35.5%. Adverse events > or =grade 3 were observed in 26 (23.8%) patients. Chemotherapy dose reduction, chemotherapy delays more than 1 week, and treatment discontinuation were observed in 33 (30.3%), 45 (41.3%), and 17 patients (15.6%), respectively. Comorbidity index according to Charlson score was significantly associated with treatment tolerance. In multivariate analysis, a CCR to CRT (P<0.01), a dose of radiotherapy > or =80% (P=0.02), and a Charlson score < or =2 (P=0.046) were identified as independent prognostic factors of overall survival. These results suggest that CRT could be considered as an effective treatment without major toxicity in elderly patients with OC.

Objectives: To assess the impact of baseline nutritional status on treatment response and survival in nonmetastatic patients with a locally advanced esophageal cancer (LAEC) treated with definitive chemoradiotherapy (CRT)., Methods: One hundred five patients with LAEC treated by definitive CRT were retrospectively included. The CRT regimen was based on an external radiotherapy (RT) delivered concomitantly to a cisplatin-based chemotherapy (CT). Patients were considered to have a complete response (CR) to CRT when no residual tumor was detected on CT scan and esophagoscopy performed 2 months after the end of CRT. Multivariate analysis of predictive factors of response to CRT and survival were performed using a logistic regression and a Cox model, respectively., Results: Mean value of baseline nutritional parameters was significantly different between nonresponder (N = 42) and responder (N = 63) patients to CRT (weight loss 10%vs 5.8%, P= 0.0047; serum albumin level 35 g/L vs 38.7 g/L, P= 0.0004; BMI 22.8 kg/m2vs 25.2 kg/m2, P= 0.01). In multivariate analysis, serum albumin level > 35 g/L was the only independent predictive factor of CR to CRT (P= 0.009). Independent prognostic factors of survival were BMI > 18 kg/m2 (P= 0.003), dysphagia Atkinson score <2 (P= 0.008), dose of RT > 50 Grays (Gy) (P < 0.0001) and CR to CRT (P < 0.0001)., Conclusions: Survival was influenced by baseline nutritional status as well as dysphagia, dose of RT, and CR to CRT. Despite the retrospective design of the study, our results may provide the concept basis for performing a prospective nutritional intervention study in patients treated by definitive CRT for an esophageal cancer.

Objectives: The impact of the histological tumour type in patients treated with definitive chemoradiotherapy (CRT) for an oesophageal cancer is not well established. The aim of this retrospective matched-pair analysis was to evaluate the clinical complete response (CCR) to definitive CRT and the outcome between 2 groups of patients., Methods: Fifty-seven patients with an oesophageal adenocarcinoma (ADC) were matched according to the tumour stage and the WHO performance as well as the CRT regimen status including 57 patients with an oesophageal squamous cell carcinoma (SCC). CRT was based on radiotherapy combined with a cisplatin-based chemotherapy., Results: A CCR was observed in 40 patients (70.2%) with an SCC as compared with 26 patients (45.6%) with an ADC (p = 0.013). SCC patients received significantly more of planned cisplatin and radiotherapy doses than ADC patients (82.0 vs. 67.7%, p = 0.042, and 92.5 vs. 84.5%, p = 0.023, respectively). In responders to CRT, local recurrence was significantly more frequent in SCC patients (52.5 vs. 26.9%, p = 0.046). Median survival in all patients as well as in responders to CRT was not different between the 2 groups., Conclusion: Our study showed that treatment completion and CCR to definitive CRT were more frequent in SCC with, however, more local recurrences in these patients. Further studies are required to confirm this difference in response rate to definitive CRT according to histological type of the tumour in oesophageal cancer., (2008 S. Karger AG, Basel.)

The diagnostic and therapeutic management of patients with soft-tissue tumors would be similar to the approach used for bone tumors if it were not for one crucial factor: the absolute necessity to recognize a sarcoma. The predominant features are the size of the tumor and its superficial or deep localization. If the tumor is small and superficial, biopsy can be associated with immediate resection without risk of dissemination to the deep tissues: this is the biopsy-resection approach. If the tumor is deep or superficial but large sized, search for locoregional spread with MRI is necessary before undertaking any surgical procedure. MRI can help guide the biopsy and plan resection if the tumor is a sarcoma. A first biopsy is necessary to establish the histological diagnosis and elaborate the therapeutic strategy. Samples should be sent immediately to the pathology lab which should examine sterile fresh tissue. Experience has demonstrated that proper rules for diagnosis and treatment are not necessarily applied initially in approximately one-fourth of all subjects with a malignant soft-tissue tumor. Besides the medical problems caused by this situation, the patient loses a chance for cure. When the tumor is a sarcoma, surgery is the basis of treatment. Complementary radiation therapy may be necessary, particularly for high-grade tumors or if the surgical margin was insufficient. Systemic or locoregional chemotherapy can also be used for high-grade or non-resectable tumors.

A recent phase I study showed that weekly cisplatin, irinotecan and concurrent radiotherapy can be administered with moderate toxicity in patients with oesophageal cancer. Patients with no prior treatment and oesophageal cancer stage I to III, performance status <3, caloric intake >1,500 kcal day(-1) were included. Chemotherapy, with cisplatin 30 mg m(-2) and irinotecan 60 mg m(-2), was administered at days 1, 8, 22, 29, and concurrently with radiotherapy at days 43, 50, 64 and 71. Radiotherapy was delivered with 50 or 50.4 Gy in 25 fractions/5 weeks. Forty-three patients were included, 10 stage I, 19 stage II and 14 stage III. Mean age was 59.2 years (range 44-79). A total of 30 out of 43 (69.8%) patients underwent all planned treatment. During induction chemotherapy, 14 severe toxicities of grade 3 or 4 in 10 patients (23.3%) were reported with 57.1% due to haematoxicity. During chemoradiotherapy, 31 severe toxicities of grade 3 or 4 with 64.5% due to haematotoxicity were reported in 18 patients. One toxic death occurred (diarrhoea grade 4). The complete clinical response rate was 58.1% (95% CI: 43.4-72.8%). Overall survival rate at 1 and 2 years was 62.8%, (95% CI, 58.3-77.3%) and 27.9% (95% CI, 13.4-41.3%), respectively. In conclusion, cisplatin-irinotecan-radiotherapy is an active and well-tolerated regimen feasible in out-patients.

Unlabelled: Impact of radiotherapy (RT) schedule on local response and duration of the 5-fluorouracil/cisplatin (5 FU/CDDP) chemotherapy (CT) on m are still questioning in chemoradiotherapy (CRT) regimen in esophageal carcinoma., Aim: Evaluate two RT schedules and two different CT durations by a retrospective comparison of the CRT regimens used by two centres between 1994 and 2000., Methods: In centre I (regimen I), patients received 2 CT concomitantly to a continuous RT (50 Gy/25 fractions/5 weeks). In centre II (regimen II), patients received 6 CT, 3 were concomitant to a split course RT (20 Gy/10 fractions x 3 courses) and 3 CT were delivered after CRT., Results: A total of 129 patients were included, 74 in centre I and 55 in centre II respectively. Main patient characteristics were similar between the two groups. Clinical complete response to CRT was significantly more frequent in regimen I (83.8% vs 65.4%; P=0.02). The median overall survival (OS) was 20 months in regimen I and 22 months in regimen II (NS). During follow-up, responder patients to CRT in regimen II experienced significant fewer metastasis (51.6% vs 27.8%; P=0.03) with a trend to an increased 5-year survival (19.4% vs 11.3%) and OS (26.5 vs 21.0 months) (NS). Grade 3-4 toxicities were not different., Conclusion: Clinical complete response to CRT was significantly more frequent with a continuous RT whereas additional CT after CRT significantly reduced metastasis occurrence. CRT regimen in esophageal carcinoma may be more effective using a continuous RT schedule and additional CT courses after CRT completion.
