Primary fallopian tube carcinoma (PFTC) is a rare and highly aggressive tumor. Twelve cases of PFTC (stages IA to IV) were analyzed by comparative genomic hybridization. The most consistent DNA gain was mapped to chromosome arm 3q in 11 of 12 cases. In six cases, the gain of 3q was present as a high level copy number increase (amplification) with a consensus region mapped to 3q26.2-qter. In the 12 cases, other frequent gains were located on chromosome arms 1q (in 11 cases), 2q (in 10), 7q (in 9), 8q (in 9), 5p (in 8), 6p (in 7), 12p (in 7), and 14q (in 6). Frequent copy number losses occurred on chromosome arms 16q (in 8 cases), 22q (in7), 6q (in 6). 8p (in 6), 18q (in 6), Xq (in 6), 1p (in 5), and 17p (in 5). All chromosomes were involved in chromosomal aberrations and the average number of copy alterations per case was 19.7. None of the 12 carcinomas revealed the presence of human papillomavirus (HPV) genomes. All of the cases exhibited crude aneuploidy. Strong p53 immunoreactivity could be observed in 10 of 12 cases while p21/WAF1 expression was low or undetectable. These results indicate that PFTC is a genomically highly unstable cancer, an observation that is in agreement with the poor prognosis associated with this tumor. A high frequency of 3q-gains has also been observed in HPV-related carcinomas of the uterine cervix. However, none of the PFTC was HPV related, suggesting that the 3q-gain is independent from HPV DNA.

Objective: To investigate and analyze symptoms in patients with different types of ovarian cancer., Method: Records of 160 women with ovarian cancer were studied in detail following the patients from first consultation to operation and diagnosis at Sodersjukhuset, Stockholm., Result: No specific group of symptoms could be linked to type or stage of ovarian cancer. Gastrointestinal symptoms were more common in patients with class 1C tumors. Only 21% complained of gynecological symptoms. Women with class 1C cancer had significantly more advanced disease than those with 2C-5C cancer as 77% had a stage III-IV tumor compared with 40% of class 2C-5C patients., Conclusion: Diagnosis of ovarian cancer is difficult due to the multitude of symptoms often appearing late in the disease. The majority of women did not experience symptoms in the genital organs. Methods to encourage early consultation should be investigated.

The prognostic influence in operable mammary carcinoma of morphologic predictors evaluated in smears of needle-biopsy aspirate and in tissue sections and of clinical stage was investigated. Size of nuclei in smears of aspirate was found to convey prognostic information of the same order of importance as the variables tubule information and mitotic frequency in tissue sections. The combination of clinical stage with variables in smears and in sections enhanced the explanatory value.

Early vocal cord carcinomas (TiS or T1) in a consecutive series of 177 patients treated by primary radiotherapy over a 10-year period 1970-79 at the Department of General Oncology, Radiumhemmet, Karolinska Sjukhuset, were analysed regarding treatment results. In 137 cases the tumours were invasive (T1N0M0) and in 40 cases carcinoma of in situ type (TiS). Patient were treated with cobalt 60 gamma irradiation in fractions of 2 Gy up to a total dose of 64 Gy delivered as split course (CRE=17.8). Minimum follow-up time was 5 years. Tumour recurred in 21 cases (12%). All but 4 patients were rescued by subsequent surgery, giving 98% total survival. Treatment failures after primary radiotherapy were analysed in detail. Failures could not be attributed to treatment irregularities. No difference in pretreatment tumour size was detected when cured patients were compared with patients who relapsed. Biological factors that cause a relative radioresistance are considered to be the main reason for radiotherapy failures in early glottic cancer.

The risk of second primary malignancy arising after therapeutic irradiation was evaluated in the Radiumhemmet series of carcinoma of the uterine cervix treated in 1914-1965. Only tumours appearing more than 10 years after irradiation were taken into account. Comparisons of observed with expected incidence showed excess of malignancies in urinary bladder, endometrium, ovaries and rectum, but not of colon carcinoma. Comparisons were made with cohorts from the Swedish Cancer Registry.

This report provides a histological review of 264 female primary breast cancers analyzed for estrogen receptor protein (ER). We also describe 5 cases of male breast cancer all of which bound estradiol specifically. Generally the ER concentrations were lower in the tumors of premenopausal women than in those of postmenopausal women. Three types of cancer with specific morphological features were shown to have ER concentrations that differed significantly from the other types of cancer. Medullary and comedo carcinoma had very low and papillary carcinoma very high levels of ER. No obvious trend in ER concentration was found in unspecified ductal carcinoma, colloid carcinoma, nor in lobular carcinoma. A positive correlation was demonstrated between ER content and degree of differentiation in ductal carcinoma. Cancer with lymphoid infiltration generally showed low ER levels.

Forty patients aged 20 years or younger at the time of the diagnosis of thyroid carcinoma were followed between 10 and 35 years (mean, 22 years). All patients had had surgery, either a total thyroidectomy or a resection. Sixteen patients received additional radiotherapy. One patient died during surgery. Two patients died of metastatic tumor growth, 5 and 14 years after the primary diagnosis, respectively. Six further patients had recurrences (1-7.5 years after first treatment) and received further treatment. At the end of the study 37 patients were alive without signs of recurrence.
