Background The purpose of this study is to evaluate the effect of postoperative chemotherapy on recurrence and survival in patients after resection of metastatic brain tumors from non-small cell lung cancers. Methods Patients who went through resection of a single metastatic brain tumor from non-small cell lung cancer from July 2001 to December 2012 were reviewed. Those selected were 77 patients who survived more than 3 months after surgery were selected. Among them, 44 patients received various postoperative systemic chemotherapies, 33 patients received postoperative adjuvant whole brain radiotherapy (WBRT). Local/distant recurrence rate, local/distant recurrence free survival, disease free survival (DFS), and overall survival were compared between the two groups. Results Among the 77 patients, there were 19 (24.7%) local recurrences. Local recurrence occurred in 7 (21.2%) of 33 patients in the adjuvant radiotherapy (RT) group and in 12 (27.3%) of the 44 patients in the chemotherapy group (p=0.542). Among the 77 patients, there were 34 (44.1%) distant recurrences. Distant recurrence occurred in 7 (21.2%) of the 33 patients in the adjuvant RT group and in 27 (61.4%) of the 44 patients in the chemotherapy group (p<0.0005). Patients’ survival in terms of local recurrence free survival, distant recurrence free survival, DFS, and overall survival was not shown to be statistically different between the two groups before and after adjusting for covariates. Conclusion There was no significant difference observed between postoperative adjuvant chemotherapy and adjuvant WBRT in terms of patients’ survival. Postoperative chemotherapy is more feasible and may be an appropriate option for simultaneous control of both primary and metastatic lesions.

Radiation therapy has an important role in postoperative treatment of neoplasms originated from central nervous system, but may induce secondary malignancies like as sarcomas, gliomas, and meningiomas. The prognosis of radiation-induced osteosarcomas is known as poor, because they has aggressive nature invasive locally and intractable to multiple treatment strategies like as surgical resection, chemotherapy, and so on. We report a case of radiation-induced osteosarcoma developed from skull after 7 years of craniospinal radiotherapy for pineoblastoma.

Objective: Patients with symptomatic brain metastases secondary to mass effect are often candidates for surgery. However, many of these surgical candidates are also found to have multiple asymptomatic tumors. This study aimed to determine the outcome of surgical resection of symptomatic brain metastases followed by chemotherapy or radiotherapy (RT) for the remnant asymptomatic lesions in non-small cell lung cancer (NSCLC) patients with multiple brain metastases. Methods: We conducted a retrospective review of the medical records of 51 NSCLC patients with symptomatic multiple brain metastases who underwent surgical resection, of whom 38 had one or more unresected asymptomatic lesions subsequently treated with chemotherapy and/or RT. Thirteen patients underwent resection of all metastatic lesions. Results: Median survival for overall patient population after surgical resection was 10.8 months. Median survival for patients with surgical resection of all brain metastases was not significantly different with patients who underwent surgical resection of only symptomatic lesions (6.5 months vs. 10.8 months; p=0.97). There was no statistically significant difference in survival according to the number of tumors (p=0.86, 0.16), or post-surgical treatment modalities (p=0.69). Conclusion: The survival time of NSCLC patients with multiple brain metastases after surgery for only symptomatic brain metastases is similar to that of patients who underwent surgery for all brain metastases. The remaining asymptomatic lesions may be treated with chemotherapy or radiotherapy. The optimal treatment modality, however, needs to be defined in prospective trials with larger patient cohort.

Gastric ulcer is a serious global health challenge, and various natural products are being investigated to prevent and manage the condition. This study evaluated the gastroprotective and ulcer healing potentials of Nigerian bee propolis flavonoid-rich extract (NPE) on acetic acid-induced gastric ulcers in albino rats. Sixty adult male albino rats (222 ± 6.4 g) randomised into 5 groups (n = 12) were studied. Group A (SHAM) was left untreated, while gastric ulcer was induced in groups B (NPE), C (omeprazole) and D (saline). Group E (PRPE) was pre-treated with NPE prior to ulcer induction. The rate of ulcer contraction, volume and pH of gastric juice, and histopathological parameters were evaluated. The results showed a significantly higher rate of contraction (P = 0.001) between days 9 and 12 (NPE > OME > PRPE > SAL) and a significant decrease (P = 0.003) in the volume of gastric juice between days 9 and 12 (NPE < OME < PRPE). Gradual increase in pH was observed in all the groups from days 3 to 12, with a significantly higher rate (P < 0.001) between day 6 and 12 (SHAM > NPE > OME > PRPE > SAL). Histological evaluation showed significantly high neutrophils and macrophages on day 6 (P = 0.006) and lymphocytes (P = 0.004) between day 6 and 12 in the OME and NPE groups. NPE showed gastroprotective and ulcer healing properties by inhibiting ulcer formation and facilitating the curation of induced ulcers and is, therefore, a valuable alternative to conventional gastric ulcer therapy, especially in poor resource settings.
