Thirty-nine women (49.4%) had clinical evidence of axillary metastasis (N1-N2) at the time of diagnosis. The regimen, the duration of treatment, and the number of cycles of NACT depended on clinical response. The choice of breast conservation therapy or mastectomy was based on the patient’s response to treatment and patient preference. All patients underwent SLNB after NACT. RESULTS: Seventy-three patients underwent breast conservation therapy, and 6 patients underwent mastectomy. Sentinel lymph nodes were identified in 98.7% of patients (in 1 patient, SLNB failed to capture 1 proven axillary metastasis), and 29 patients underwent see more full axillary lymph node dissection.

Fourteen patients (17.7%) had no residual carcinoma (invasive

or ductal carcinoma in situ) in their breast, 5 patients (6.3%) had residual ductal carcinoma in situ (only), and 60 patients (75.9%) had residual invasive carcinoma. One false-negative SLNB was reported in the group of 23 patients who underwent full axillary dissection after a negative SLNB. No patient had a subsequent axillary recurrence. CONCLUSIONS: SLNB after NACT was feasible in virtually all patients and accurately selected patients who required complete level I and 11 axillary dissection. NACT frequently downstaged the axilla, converting patients with AZD9291 N1-N2 lymph node status to NO status and also avoiding full axillary dissection in these patients. Cancer 2010;116:1243-51.

“Aims and Objectives: Industrial workers are constantly exposed to benzene, especially at the production unit. The present investigation explores any association of the outcome of various reproductive malfunctions in terms of infertility and other related factors as a result of benzene exposure. Methodology: Blood and semen samples were collected from total 160 industrial workers exposed to benzene and 200 nonoccupationally exposed control subjects. We investigated macroscopic and microscopic semen parameters in the present study population. Body fluid benzene analysis was done by learn more Head Space chromatography.

The sperm DNA integrity was determined by modified alkaline single-cell gel electrophoresis or the comet assay method. Results: No significant changes were observed in macroscopic semen parameters. A duration-dependent decrement in total sperm count and the percentage of motility was observed among the benzene-exposed industrial workers (p < 0.05). A duration-dependent increment of abnormal sperm morphology was observed among the benzene-exposed industrial workers (p < 0.01). A significant increase in comet tail length was observed in the exposed groups (p < 0.01) in comparison to the controls. In regression analysis, the data were observed to be significant at the level of p < 0.05 for Group II industrial workers (t = 2.301). Conclusion: Sperm integrity is considered one of the major factors in male infertility.
