Aim: We investigated the prognostic potential of pretherapy measurement of the neutrophil/lymphocyte ratio (NLR) in patients (n = 56) with non-small-cell lung cancer deemed suitable for treatment with nivolumab.

Materials & Methods: This was a multicenter, noninterventional, retrospective data analysis, involving five oncology centers.

Results: Patients with prenivolumab NLR values of <5 and ≥5 had respective median overall survival (OS) values of 14.

Background: In the phase III SOLE trial, the extended use of intermittent versus continuous letrozole for 5 years did not improve disease-free survival in postmenopausal women with hormone receptor-positive breast cancer. Intermittent therapy with 3-month breaks may be beneficial for patients' quality of life (QoL).

Methods: In the SOLE QoL sub-study, 956 patients completed the Breast Cancer Prevention Trial (BCPT) symptom and further QoL scales up to 24 months after randomisation.

Purpose To describe benefits and toxicities of adjuvant endocrine therapies in women younger than 35 years with breast cancer (n = 582) enrolled in the Suppression of Ovarian Function Trial (SOFT) and Tamoxifen and Exemestane Trial (TEXT). Methods In SOFT, women still premenopausal after surgery with or without chemotherapy were randomly assigned to tamoxifen alone, tamoxifen plus ovarian function suppression (OFS), or exemestane plus OFS. In TEXT, all received OFS with or without concomitant chemotherapy and were randomly assigned to exemestane plus OFS or tamoxifen plus OFS.

Purpose: Endobronchial metastasis (EBM) originating from primary cancers outside the lung is rare. External beam radiotherapy is often attempted for control of symptoms with variable effectiveness and retreatment is challenging if symptoms recur. There is limited documentation of high-dose-rate brachytherapy for EBM in the literature.

Over the past few decades, the systemic therapy of breast cancer (early and advanced) has changed considerably. For the past 40-50 years, and since the discovery and further therapeutic use of tamoxifen, a selective estrogen receptor modulator, breast cancer treatment has become the model for the development and success of tailored medical treatment. Much still needs to be done in improving outcomes for all patients with breast cancer, and especially for those who have advanced breast cancer, a challenging area for medical oncologists.

Dupuytren's contractures associated with the BRAF inhibitor vemurafenib: a case report.

J Med Case Rep

July 2015

Sandton Oncology Centre, 159 Rivonia Road, Morningside, Sandton, Johannesburg, Gauteng, 2199, South Africa.

Introduction: Two previous cases of the development of Dupuytren's contractures were reported in association with BRAF inhibitor treatment for BRAF V600E mutation-positive metastatic melanoma and metastatic papillary thyroid carcinoma. We reported on a third case with a slower onset of presentation.

Case Presentation: A 66-year-old white man was diagnosed with a BRAF V600E mutated metastatic cutaneous melanoma.

Purpose: Obstructive symptoms that affect quality of life (QOL) are commonly caused by endobronchial disease in many patients with locally advanced, inoperable lung cancer. High-dose-rate endobronchial brachytherapy (HDREBBT) has been used to palliate these symptoms, yet its role is not well defined in the literature.

Methods And Materials: Ninety-eight patients with locally advanced, inoperable lung cancer received HDREBBT.

Bone is the most common site of distant metastases in breast cancer that can cause severe and debilitating skeletal related events (SRE) including hypercalcemia of malignancy, pathologic fracture, spinal cord compression and the need for palliative radiation therapy or surgery to the bone. SRE are associated with substantial pain and morbidity leading to frequent hospitalization, impaired quality of life and poor prognosis. The past 25 years of research on the pathophysiology of bone metastases led to the development of highly effective treatment options to delay or prevent osseous metastases and SRE.

Bone targeted therapies in early breast cancer.

Curr Treat Options Oncol

December 2011

Sandton Oncology Centre, Sandton, Parklands, Johannesburg, South Africa.

Bisphosphonates have emerged as an important tool in the supportive care of women with early breast cancer. Whereas traditionally, these drugs have been part of the treatment of osseous metastasis, the key role of bisphosphonates in preserving bone health in patients with early breast cancer cannot be overemphasised. Currently the most established use of bisphosphonates in early breast cancer patients is in women receiving hormonal blockade, mostly aromatase inhibitors (AI), with concomitant osteopenia.

The aim of this multicentric phase II study was to investigate the efficacy and toxicity of a combination of chemotherapy containing paclitaxel (Taxol) and a novel compound, a liposomal encapsulated doxorubicin (Caelyx), as first line therapy for patients with metastatic breast cancer. Thirty-four patients with advanced breast cancer were treated with a combination of paclitaxel 175 mg/m2 and liposomal doxorubicin 30 mg/m2, every 3 weeks. The combination chemotherapy was effective in 73% of the patients (ITT) (95% CI 55-86%) (7 complete and 18 partial responses).

Fourteen patients with metastatic malignant melanoma that had failed to respond to standard dacarbazine-based chemotherapy treatment were entered into a phase II study of pegylated liposomal doxorubicin (Caelyx) given as a single intravenous injection at a dose of 50 mg/m(2) at 28 day intervals. No objective responses were documented. Treatment was well tolerated.

Current cytotoxic therapy has been of limited benefit to patients with malignant pleural mesothelioma. Single agent chemotherapy has been extensively evaluated in small series of phase II clinical trials, with disappointing responses. Docetaxel, an effective taxane in the treatment of advanced breast cancer and non-small-cell lung cancer, was administered intravenously at a dose of 100 mg/m2 every 3 weeks to 30 chemotherapy naive patients with malignant pleural mesothelioma in a prospective multi-institutional phase II clinical trial.

Background: This study provides a direct randomized comparison of a new-generation, non-steroidal aromatase inhibitor, anastrozole (Arimidex), with a steroidal aromatase inhibitor (formestane) with respect to oestrogen (oestradiol, oestrone, and oestrone sulphate) suppression and tolerability.

Patients And Methods: Sixty postmenopausal women with advanced breast cancer were randomized to receive either anastrozole 1 mg once daily orally (n = 29), or formestane 250 mg once every two weeks by intramuscular injection (n = 31). Treatment was continued until progression of disease or withdrawal from the study.
