Delaying surgery after neoadjuvant chemoradiotherapy improves prognosis of rectal cancer.

AIM: To investigate the prognostic effect of a delayed interval between neoadjuvant chemoradiotherapy (CRT) and surgery in locally advanced rectal cancer. METHODS: We evaluated 87 patients with locally advanced mid- or distal rectal cancer undergoing total mesorectal excision following an interval period after neoadjuvant CRT at Sisli Hamidiye Etfal Training and Research Hospital, Istanbul between January 2009 and January 2014. Patients were divided into two groups according to the interval before surgery: < 8 wk (group I) and ≥ 8 wk (group II). Data related to patients, cancer characteristics and pathological examination were collected and analyzed. RESULTS: When the distribution of timing between group I (n = 45) and group II (n = 42) was viewed, comparison of interval periods (median ± SD) of groups showed a significant difference of as 5 ± 1.28 wk in group I and 10.1 ± 2.2 wk in group II (P < 0.001). The median follow-up period for all patients was 34.5 (9.9-81) mo. group II had significantly higher rates of pathological complete response (pCR) than group I had (19% vs 8.9%, P = 0.002). Rate of tumor regression grade (TRG) poor response was 44.4% in group I and 9.5% in group II (P < 0.002). A poor pathological response was associated with worse disease-free survival (P = 0.009). The interval time did not show any association with local recurrence (P = 0.79). CONCLUSION: Delaying the neoadjuvant CRT-surgery interval may provide nodal down-staging, improve pCR rate, and decrease the rate of TRG poor response.

Malignant fibrous histiocytoma of the breast in young male patient: a case report and a review of the literature.

MALIGNANT FIBROUS HISTIOCYTOMA (MFH) IS A FAIRLY COMMON TUMOR IN THE DEEP SOFT TISSUES: the most frequent primary sites are the lower (49%) and upper (19%) limbs, but it has been reported even in the retroperitoneum and abdomen (16%), while localization in the breast is extremely rare (1-2). Breast cancer is rarely seen in males, accounts for approximately 1% of all breast cancer, and the breast sarcomas constitute less than 1% of breast tumors in both sexes. In the review of the literature, this is the third male and first young male with MFH. Here, we present a 37-years-old male patient who is diagnosed to have malignant fibrous histiocytoma in a variant of pleomorphic fusiform cell localized in the left breast. Following the wide local excision, the patient was given an adjuvant 50 Gy of external radiotherapy. He remained alive and well after 42 months of followup. We believe that reporting such few cases would contribute to forming treatment algorithms of rare tumors.
