Approximately 30 to 40% of patients with advanced lung cancer will develop bone metastases in the course of their disease, resulting in a significant negative impact on both morbidity and survival. Skeletal complications of bone metastases include pain, pathologic fractures, spinal cord compression, and hypercalcemia. Total medical care costs are greater among patients with bone metastases who develop skeletal complications. A randomized phase III trial of the third generation bisphosphonate zoledronic acid has shown clinical benefit in the management of a subgroup of patients with bone metastases from lung cancer. Zoledronic acid treatment was associated with a reduction in both the risk of, and time to, a skeletal-related event. One of the markers of bone resorption, N-telopeptide, is both prognositic for development of skeletal-related events and predictive for benefit from zoledronic acid. In preclinical models, bisphosphonates have also demonstrated antitumor activity and are therefore currently being evaluated in adjuvant trials. Inhibition of the receptor activator of nuclear factor kappa B ligand-RANK pathway can reduce osteoclast-mediated bone resorption, and trials comparing receptor activator of nuclear factor kappa B ligand inhibitors with bisphosphonates are ongoing, including patients with lung cancer. In this article, we review the management of bone metastases and hypercalcemia as well as potential future directions for bone directed therapies in patients with lung cancer.
Ovarian dysgerminomas are rare entity and account for only about 2% of all malignant ovarian neoplasm. The aim of this study was to evaluate the clinicopathologic characteristics, treatment, long-term survival, and fertility outcome of women diagnosed with ovarian dysgerminoma at our institution. Sixty-five women with histologically proven pure ovarian dysgerminoma were identified in this retrospective study. They were treated at King Faisal Specialist Hospital, Riyadh; Saudi Arabia between 1976 and 2010. The median age was 20 years. The most frequent symptoms at presentation were abdominal pain and abdominal/pelvic mass. Thirty-three patients (50.7%) presented with stage I, 2 (3.1%) had stage II, 22 (33.8%) had stage III, and 4 (6.2%) had stage IV (4 unknown stage). Unilateral oophorectomy was performed in 50 patients (76.9%) while bilateral oophorectomy±hysterectomy was done in 12 patients (18.4%). Three patients had biopsy only. Forty patients (61.5%) received only chemotherapy, and 4 patients (6.2%) received radiotherapy alone. Recurrence was observed in 6 patients (9.2%). With median follow-up of 54 months, the 5-year disease-free survival (DFS) and overall survival (OS) were 88 and 95%, respectively. On univariate analysis, adjuvant chemotherapy was independent better prognostic factor for DFS (HR, 0.09; 95% CI, 0.01-0.84; P=0.034). Of the 50 patients treated with fertility-sparing surgery, 16 patients (32%) achieved pregnancy with 14 live births. Patients with pure ovarian dysgerminoma have excellent long-term outcome. There is no difference at outcome between fertility-sparing and nonconservative surgeries. Adjuvant chemotherapy was associated with significant improvement in DFS. It is possible to maintain good reproductive function after conservative surgery followed by chemotherapy in our series.
Background: In a Spanish Lung Cancer Group (SLCG) phase II trial, the combination of BRCA1 and receptor-associated protein 80 (RAP80) expression was significantly associated with outcome in Caucasian patients with nonsmall-cell lung cancer (NSCLC). The SLCG therefore undertook an industry-independent collaborative randomized phase III trial comparing nonselected cisplatin-based chemotherapy with therapy customized according to BRCA1/RAP80 expression. An analogous randomized phase II trial was carried out in China under the auspices of the SLCG to evaluate the effect of BRCA1/RAP80 expression in Asian patients.Patients and methods: Eligibility criteria included stage IIIB-IV NSCLC and sufficient tumor specimen for molecular analysis. Randomization to the control or experimental arm was 1 : 1 in the SLCG trial and 1 : 3 in the Chinese trial.

BACKGROUND:Lung cancer management is getting more complex due to the rapid advances in all aspects of diagnostic and therapeutic options. Developing guidelines is critical to help practitioners provide standard of care.METHODS:The Saudi Lung Cancer Guidelines Committee (SLCGC) multidisciplinary members from different specialties and from various regions and healthcare sectors of the country reviewed and updated all lung cancer guidelines with appropriate labeling of level of evidence. Supporting documents to help healthcare professionals were developed.RESULTS:Detailed lung cancer management guidelines were finalized with appropriate resources for systemic therapy and short reviews highlighting important issues. Stage based disease management recommendation were included. A summary explanation for complex topics were included in addition to tables of approved systemic therapy.CONCLUSION:A multidisciplinary lung cancer guidelines was developed and will be disseminated across the country.
Patients presenting with advanced-stage disease are higher among Saudis than those reported in global literature. Despite high intermarriage rates, reported family history for related cancers was quite low in this cohort. Notably, this is the first study evaluating EOC in Saudi patients.
BACKGROUND AND OBJECTIVEUterine papillary serous cancer (UPSC) represents only 10% of all uterine cancers and is associated with a significantly worse prognosis compared with other histological types of endometrial cancers. It closely resembles the behavior of ovarian carcinoma.DESIGN AND SETTINGRetrospective study in a referral center covering period from February 1989 to January 2009.PATIENTS AND METHODSEighteen patients who underwent definitive surgery followed by adjuvant therapy—platinum-based chemotherapy, radiotherapy, or both—were reviewed. Median age was 62 years (range, 52–76 years). All patients underwent total abdominal hysterectomy and salpingo-oophorectomy. Positive lymph nodes were found in 4 of 7 patients who underwent lymph node sampling/dissection. Seven patients had stage I/II disease, whereas 11 patients had stage III disease. Six patients received chemotherapy, 5 patients received radiation therapy, while 7 patients received both chemotherapy and radiation therapy.RESULTMedian follow-up was 27 months. The median survival and relapse-free survival were 33 and 23 months, respectively. Eight patients were alive and free of disease, of whom 5 patients were stage I/II and 4 patients were stage III. Distant metastasis was the most common site of relapse. Early stage (I/II) was associated with significant improvement in relapse-free survival (RFS) and overall survival (OS) (P=.004 and P=.05, respectively). The combined-modality treatment including chemotherapy-radiotherapy showed statistically significant improvement in RFS (P=.012), while the improvement in OS did not reach statistical significance (P=.12).CONCLUSIONThis study indicates that postoperative combined treatment with chemotherapy and radiation therapy plays a role in the management of UPSC by improving RFS. Distant metastasis remains the major site of relapse. Future studies using combined-modality therapy are needed to improve the outcome in patients with UPSC.
