[Male secondary breast cancer after treatment for Hodgkin's disease. Case report and review of the literature].

Hodgkin's disease is now curable in more than 50% of cases, due to its chemo- and radio-sensitivity. However, treatment exposes to a risk of secondary cancer varying from 1 to 10% depending on chemoradiotherapy doses and schedules. We report a case of secondary breast cancer associated with a secondary thyroid cancer observed in a 24-year-old man treated when he was 13 years old by vinblastin and radiation for stage IIA, a Hodgkin's disease.

[Radiation-induced glioblastoma and myxoma after treatment for undifferentiated carcinoma of the naspharynx].

Radio-induced tumor have been known for a long time to occur after treatment of cancer during childhood. This entity is exceptional following radiotherapy of the cavum. Skull and facial osteosarcoma were described after treatment of UCNT. We report two observations of radio-induced tumors arising, respectively three and seven years after treatment of UCNT. The first one is a temporoparietal glioblastoma and the second is a rhino- and pharyngeal myxoma. The two patients are alive after treatment of the second tumor. The delay of appearance of these tumors, their situation in the field's irradiated and dose received suggests their radio-induced nature. However, the cytogenetic study is necessary to confirm the implication of radiotherapy in the genesis of these cancers.

[Intraoperative brachytherapy in the management of keloids. Apropos of 114 cases] .

PURPOSE: Keloid scars are unsightly, especially when located on the face or bare zones. The purpose of this study was to evaluate the therapeutic results of intraoperative brachytherapy in the management of keloids. MATERIAL AND METHODS: This retrospective study was based on the study of 82 patients with keloids treated in Salah Azaiz Institute (Tunisia) between 1982 and 1994 (65 women and 17 men). The mean age of patients was 23.4 years (+/- 8.4). A total of 114 lesions have been treated with surgical resection and intraoperative brachytherapy using an iridium source placed under the surgical scar. The length of iridium was chosen with the result that the radioactive thread exceeded 5 mm on each side of the surgical scar. The iridium source was loaded less than six hours after resection. Average iridium activity was 1.5 +/- 0.3 mCi/cm. Average iridium length was 56.8 +/- 34 mm. The referred isodose chosen for the target volume included the surgical scar and a margin of 5 mm around the iridium source, which was placed under the surgical scar. The average administered dose was 20.4 Gy (+/- 3.2 Gy). RESULTS: The 2-year local control rate was 87% for the whole group of lesions treated (n = 114). Local control rate of keloids processed by resection and intraoperative brachytherapy as the first treatment (59 cases) was 96% at two years. This rate was better than the local control of lesions that had been previously treated with anterior surgical resection (84% in 55 cases). For the latter group, lesions treated with a dose of more than 20 Gy had better local control, but the difference was not statistically significant (87 vs. 65% at two years, P = 0.41). CONCLUSION: Intraoperative brachytherapy is effective for improving local control of keloids and preventing a recurrence. A rigorous technique and an adequate dose according to previous surgical treatment allows very good results.

[Cutaneous lymphoma in Tunisia: clinical profile and therapeutic results].

PURPOSE: The aim of this retrospective study was to investigate therapeutic result of cutaneous lymphoma in Tunisia. PATIENTS AND METHODS: Between January 1969 and June 1994, 100 patients with cutaneous lymphoma were referred either to Salah Azaiz Institute or the other University Hospitals of Tunisia. Fifty-one patients had epidermotropic lymphoma and 49 non-epidermotropic lesions. Eighty-seven patients received complete treatment. Puvatherapy and other local dermatologic treatments were used for early stage mycosis fungoïdes. Thirty-two patients benefited from radiotherapy, with curative dose in 28 cases. Chemotherapy including anthracyclin agents was used for high grade lymphoma. Thirteen patients had association of radiotherapy and chemotherapy. RESULTS: Five-year survival rates were 50% for patients with epidermotropic lesions and 56% for patients with non-epidermotropic cutaneous lymphoma. Statistical study has not identified any significant prognosis factor. CONCLUSION: Radiotherapy and chemotherapy are both effective. Treatment should depend on stage and histologic type.

[Incidence of amplification of the C-erb B2/Her-2/neu gene in human breast cancer].

Activation of cellular proto-oncogenes can be detected in several human cancers. In the current study, alterations of C-erb B2 gene in primary human breast cancers were investigated. It was found to be amplified from 2 to 30 fold in 25% of the tumors. Correlations of gene amplification with several disease parameters was evaluated.
