Article: Trichilemmal pilar tumor of the scalp: a case report.
[show abstract] [hide abstract]
ABSTRACT: Proliferating trichilemmal tumors (PTTs) are uncommon exuberant growths of cells derived from the external root sheath. They tend to occur in older women, with a predilection for the scalp. Wide local excision has been the standard treatment. Recent reports have described a rare malignant variant with an aggressive clinical course and a propensity for nodal and distant metastases which, therefore, merits aggressive treatment.

Article: Medullary carcinoma of the breast: ten year clinical experience of the kuwait cancer control centre.
[show abstract] [hide abstract]
ABSTRACT: Background: Medullary carcinomas of the breast account for fewer than 7% of all invasive breast cancers. Some investigators include medullary carcinomas in the favourable histologic subtype, despite its aggressive histologic appearance. However, others fail to confirm its favourable prognosis. Methods: This was a retrospective analysis of sixty-one (61) cases of breast cancer cases diagnosed with Medullary Carcinoma, presenting to the Kuwait Cancer Control Center between 1995 and 2005. Results: Median survival time was 122 months and the seven-year disease free survival was 82%. Overall survival rate was not assessed as no cases died during the study period. No cases were metastatic from the start and only eight cases developed metastases, local recurrence or contralateral breast primary. 68.8% of the cases were Stage I or IIA (i.e. no lymph node affection). Conclusion: There is no overt favourable prognosis of medullary carcinoma when compared to invasive ductal carcinoma. Prognosis is more related to stage than histologic subtyping. The majority of cases were negative estrogen and progesterone receptor status and node negative.

Article: Hyperfractionated Radiation Theraphy and Concurrent Chemotheraphy for advanced Head and Neck Cancer.

ABSTRACT: Purpose: To investigate the feasibility of combining hyperfractionated radiotherapy regimen with concomitant chemotherapy and to assess its toxicity in patients with advanced head and neck carcinoma (HNC). Progression free survival (PFS) and overall survival (OS) were set as secondary end points. Patients and Methods: Between November 2003 and November 2007, 48 patients with stage III and IV HNC who met the eligibility criteria were enrolled in the study. Hyperfractionated Radiation consisted of 120 Gys twice daily, 6 hours apart, for a total of 69.6 Gys in 58 fractions over 6 weeks and boost of 6 Gys in 3 fractions in case of residual disease. Three cycles of concurrent chemotherapy in the form of Cisplatin 75 mg/ m² on day 1 and Fluorouracil 750 mg/m² 24 hour infusion on day 1-4 during weeks 1, 4 and 6 of irradiation. Results: 48 patients have completed the treatment to date. The median radiation dose was 72 Gys including the boost to residual lymph node or primary site. The treatment was delivered in a median overall period of 54 days, with a recorded median delay of 7 days. Grade 4 skin toxicity was experienced by 4.1% of patients only. Therapy was well tolerated (grade 3 mucositis in 21%, grade 4 in 26%, grade 3 leukopenia in 10%). Weight loss of more than 10 kg was reported in 10 (16.7%) of the cases. The most common late toxicity was mild to moderate xerostomia which was encountered in 34 (70.8%) cases and improved thereafter. Hypothyroidism was encountered in 7 (14.6%) of the cases. Complete response (CR) was observed in 40 patients (83.3%). Partial response (PR) was achieved in the remaining 8 patients (16.7%). Disease relapse occurred in 9 patients (18.8%) after complete response and 2 patients developed progressive disease after partial response. 3 patients relapsed locally, 5 patients developed distant metastasis and 1 patient developed both local and distant metastasis. 2 patients (4.1%) died of treatment complications, 8 patients (16.7%) died with progressive locoregional, and metastatic disease. The 2- year disease free survival was 77% and the 2- year overall survival was 79%. Conclusion: Hyperfractionated radiotherapy and concurrent chemotherapy is tolerable. Results regarding LC and OS are encouraging as compared to conventional radiotherapy and concurrent chemotherapy.
