Treatment and outcomes of patients with metastatic spinal cord compression: a double-center study.

OBJECTIVE: Spinal metastases may only affect the bone tissue and result in spinal instability or may additionally result in epidural compression, leading to neurological deficits. Surgery has emerged as a popular method in treating metastatic epidural spinal cord compression (MESCC) due to the advances in surgical techniques and instrumentation. In this study, we evaluated patients with MESCC regarding neurological status, pain status, and survival rates, and presented our experience managing MESCC. PATIENTS AND METHODS: Clinical and radiographic records of 53 patients diagnosed with MESCC between January 2011 and March 2017 were retrospectively evaluated. The study included patients with a pathological diagnosis of primary cancer, those who complained of spinal metastasis, and those who had indications of MESCC on Magnetic Resonance Imaging (MRI). Bone structure and spinal stability were evaluated using assessed Computed Tomography (CT), and metastatic spread was considered using assessed Positron Emission Tomography (PET) in suitable cases. For each patient, the presence of a tumor compressing the spinal cord, age, gender, preoperative, and postoperative American Spinal Injury Association scores (ASIA), Tokuhashi prognostic score (TPS), affected spinal segment, pathological diagnosis, preoperative, and postoperative Visual Analog Scale (VAS), the status of spinal stability, follow-up period, and complications were evaluated. RESULTS: Forty-five patients (82.2% of them were women) underwent surgery with a mean age of 58.29 ± 15.14 years. The most frequent type of primary tumor was multiple myeloma (33.9%), followed by lung (24.6%), gastric (7.5%), and prostate (5.7%). The most common site of metastasis was the thoracic region (43.4%), followed by lumbar (24.5%), multiple (24.5%), and cervical (5.7%). The analysis indicated that a significant difference was found between the survival rates of the TPS categories. CONCLUSIONS: Common symptoms of MESCC include spinal pain and neurological deficit below the level of the injury. Prompt surgical treatment followed by oncological treatment leads to significant neurological recovery, more prolonged survival, pain relief, and improved quality of life in patients with a short survival time. Oncological treatments, including radiotherapy (RT), should be recommended after surgical treatment.

Real-world Treatment Patterns and Outcomes in Stage III Non-small Cell Lung Cancer: Middle East and Africa - KINDLE Study.

INTRODUCTION: The Middle East and Africa (MEA)-KINDLE, as part of a real-world global study, evaluated treatment patterns and survival outcomes in stage III non-small cell lung cancer (NSCLC) in the MEA. MATERIALS AND METHODS: Retrospective data were analyzed from 33 centers for patients diagnosed between January 01, 2013, and December 31, 2017. Descriptive analyses included clinical-demographics and treatment patterns; inferential statistics evaluated an association of first-line treatment with progression-free survival (PFS) and overall survival (OS). RESULTS: Of 1,046 patients enrolled, the median (range) age was 61.0 years (24.0-89.0); 83.2% were men, 80.8% were current or past smokers, 58.9% had stage IIIA disease, 47.8% had adenocarcinoma and 20.0% of tested (35/175) had epidermal growth factor receptor mutations. Of 86.0% of patients receiving an initial therapy, about 16% underwent surgical resection. Concurrent chemoradiotherapy (cCRT) (32.3%) was the most frequent treatment modality followed by chemotherapy (CT) alone (19.6%) and sequential CRT (12.1%). Median PFS and OS (months, 95% CI) were 11.8 (10.6, 12.4) and 22.9 (21.2, 26.3), respectively for the overall MEA subset. OS (months) was highest with surgery-based therapies for stage IIIA (IIIA: 37.3, IIIB: 24.1) followed by cCRT (IIIA: 28.9, IIIB: 24.4). Female gender, adenocarcinoma, and cCRT or Sx+CRT in first-line were associated with higher OS (P < .05). CONCLUSIONS: The data reveal an unmet need in stage III NSCLC with worse PFS and OS in the MEA subset than in the global cohort. Better access to newer therapies and quality care will be crucial in improving patient outcomes in the MEA.

The significance of immunohistochemical expression of Ki-67, p53, p21, and p16 in meningiomas tissue arrays.

Although histologic grading of meningiomas has prognostic and clinical implications, it is difficult in some cases to predict the outcome of patients. There have been several efforts to evaluate the use of different immunohistochemical markers for predicting meningioma prognosis. We analyzed the immunohistochemical expression of Ki-67, p53, p21, p16, and PTEN proteins in 130 meningiomas (64 benign, 39 atypical, and 27 malignant meningiomas) using tissue microarray. The tumors were graded according to the World Health Organization classification. There was a statistically significant correlation between the expression of Ki-67, p53, p21, p16, and the grade of meningiomas (p0.001). By ordinal logistic regression, p53 and Ki-67 were significantly associated with grade, and an increase of 1% in the labeling index of these markers resulted in an increase in the risk of raising the grade by 2.17 and 1.49, respectively. Histological grade, p53, Ki-67 labeling indices, and overexpression of p16 were strongly associated with decreased event-free survival in univariate analysis. In contrast, multivariate analysis revealed that only tumor grade is an independent factor for predicting meningioma recurrence. We conclude that the Ki-67 and p53 labeling indices are useful additional tools in discriminating atypical from benign or anaplastic meningiomas, especially in histological borderline cases.

Adjuvant chemoradiation for patients with adenocarcinoma of the pancreas: an expirence of single institute.

Only a small percentage of patients with pancreatic cancer have limited disease suitable for curative resection. Even with surgery, patients often have poor long-term survival due to relapse of the disease. There are controversies about the adjuvant treatment of these patients. We reported the survival of resected pancreatic cancer from a single institute. About 128 consecutive patients who had complete resection of the pancreatic ductal adenocarcinoma were evaluated, retrospectively. Chemoradiotherapy (45 Gy plus 5-fluorouracil) was given to 63 patients. Fifty-five patients declined to take chemoradiotherapy or with poor performance status were observed without additional treatment. Eight patients took only chemotherapy and two patients took only radiotherapy. The median survival of chemoradiotherapy group was significantly higher than the observation group (13 months vs. 4 months, respectively; P < 0.001). In multivariate analyses the most important factors improving survival were the application of chemoradiation (P < 0.001), low-level serum LDH (P = 0.026), good performance status (P = 0.033) and low serum CA19-9 (P = 0.037). Although adjuvant chemoradiotherapy has a significant survival benefit when compared with the observation group, the survival data are still poor for pancreatic cancer. Therefore, we need more effective additional or adjuvant treatment modalities.

Reactive nodular fibrous pseudotumor involving the pelvic and abdominal cavity: a case report and review of literature.

There are several entities that can present with multiple nodular lesions within the peritoneal cavity, such as "disseminated peritoneal leiomyomatosis," "peritoneal fibrosis," "calcifying fibrous pseudotumor," and the recently described lesion of "reactive nodular fibrous pseudotumor of the gastrointestinal tract and mesentery." Here we present one such lesion in a 28-year-old woman with a history of dysmenorrhea and ergotamine use for migraine attacks. Intraoperative exploration of our patient disclosed numerous nodules located throughout the pelvic and abdominal peritoneum. Histopathologically, these lesions were fibrocollagenous nodules composed of sparse wavy spindle cells within hyalinized "keloid-like" collagen surrounded by an inflammatory infiltrate. Some of the nodules were associated with small foci of endometriosis. We believe this lesion is best described by the term "reactive nodular fibrous pseudotumor" and that endometriosis and the use of ergotamine derivatives may be contributing factors.
