ABSTRACT
Purpose. In the literature, small number of study has addressed time of recurrence in breast cancer. We analyzed clinicopathological factors predicting early or late recurrence in breast cancer patients and also prognostic factors related with recurrence-free survival (RFS) in recurrent patients. Patients/methods. We evaluated retrospectively 1980 breast cancer patients. Relapsed was defined as early if it was occured first 5 year of follow-up (Group 1) and late if it was occured after 5 years (Group 2). The clinicopathological factors were compared in respect of time of recurrence. The prognostic factors were evaluated using univariate and multivariate analyses. Results. Recurrence wase detected in 141 patient during follow-up. Tumors recurred after 5 years more likely to have lower stage (p = 0.05), tumors without lymphovascular invasion (LVI) (p < 0.001) and perineural invasion (PNI) (p = 0.01), and also HER2 negative (p < 0.001). The median RFS time and 5 years RFS rates were 42.9 months and 31.9 %, respectively. LVI (p = 0.01), PNI (p = 0.03), HER2 (p = 0.003), progesterone receptor (PR) (p = 0.04), the presence of neoadjuvant chemotherapy (p = 0.003), adjuvant hormonotherapy (p = 0.05) were found to be related with RFS. Axillary lymph node metastasis (p = 0.05) and the presence of PNI (p = 0.009) were poor prognostic factors for early recurrent group. PR-positive tumors (p = 0.001) and luminal subtypes (p = 0.03) had instances of late recurrences significantly. Conclusions. Clinicopathological factors predicting the recurrence time in breast cancer were important to modify adjuvant therapy (AU)

PURPOSE: Small cell lung cancer (SCLC) has a high relapse rate despite being very chemosensitive. The efficacy of second-line treatment is dismal. Our aim was to evaluate the outcome of second-line treatment. METHODS: We retrospectively assessed data of 120 SCLC patients who failed first-line treatment and received second-line treatment at three medical oncology centers. RESULTS: Median age of group was 58. 82 % had an ECOG PS of 0-1 at the time of relapse. 39 % were at limited stage (LS) at the time of diagnosis. Patients who progressed more than 3 months after first-line therapy were categorized as having platinum-sensitive disease (PSD) (64 %). The number of patients who received platin-based combination treatment was 33 (27 %). The median OS time starting from the initiation of second-line treatment was 7 months. Multivariate analysis identified PS (p = 0.006), extent of disease at diagnosis (0.014) and PSD (0.001) as the independent prognostic factors for survival. Subgroup analyses of the patients with PSD indicated platin rechallenge yields higher progression-free survival, overall survival and overall response rate. CONCLUSION: Patients with good ECOG PS,who have PSD or initially presenting with LS, have a good prognosis and in patients with PSD, platinum-based therapy would be more appropriate (AU)
