The PARTNER trial of neoadjuvant olaparib with chemotherapy in triple-negative breast cancer.

PARTNER is a prospective, phase II-III, randomized controlled clinical trial that recruited patients with triple-negative breast cancer, who were germline BRCA1 and BRCA2 wild type. Here we report the results of the trial. Patients (n = 559) were randomized on a 1:1 basis to receive neoadjuvant carboplatin-paclitaxel with or without 150 mg olaparib twice daily, on days 3 to 14, of each of four cycles (gap schedule olaparib, research arm) followed by three cycles of anthracycline-based chemotherapy before surgery.

Imaging Modality and Frequency in Surveillance of Stage I Seminoma Testicular Cancer: Results From a Randomized, Phase III, Noninferiority Trial (TRISST).

Purpose: Survival in stage I seminoma is almost 100%. Computed tomography (CT) surveillance is an international standard of care, avoiding adjuvant therapy. In this young population, minimizing irradiation is vital.

Clinical Outcomes of a Randomized Trial of Adaptive Plan-of-the-Day Treatment in Patients Receiving Ultra-hypofractionated Weekly Radiation Therapy for Bladder Cancer.

Purpose: Hypofractionated radiation therapy can be used to treat patients with muscle-invasive bladder cancer unable to have radical therapy. Toxicity is a key concern, but adaptive plan-of the day (POD) image-guided radiation therapy delivery could improve outcomes by minimizing the volume of normal tissue irradiated. The HYBRID trial assessed the multicenter implementation, safety, and efficacy of this strategy.

Toxicity and Patient-Reported Outcomes of a Phase 2 Randomized Trial of Prostate and Pelvic Lymph Node Versus Prostate only Radiotherapy in Advanced Localised Prostate Cancer (PIVOTAL).

Purpose: To establish the toxicity profile of high-dose pelvic lymph node intensity-modulated radiation therapy (IMRT) and to assess whether it is safely deliverable at multiple centers.

Methods And Materials: In this phase 2 noncomparative multicenter trial, 124 patients with locally advanced, high-risk prostate cancer were randomized between prostate-only IMRT (PO) (74 Gy/37 fractions) and prostate and pelvic lymph node IMRT (P&P; 74 Gy/37 fractions to prostate, 60 Gy/37 fractions to pelvis). The primary endpoint was acute lower gastrointestinal (GI) Radiation Therapy Oncology Group (RTOG) toxicity at week 18, aiming to exclude a grade 2 or greater (G2+) toxicity-free rate of 80% in the P&P group.

Assessment of chemotherapy-induced peripheral neuropathy using the LDIFLARE technique: a novel technique to detect neural small fiber dysfunction.

Introduction: The diagnosis and quantification of chemotherapy-induced peripheral neuropathy (CIPN) remains a challenge. Conventional methods including quantitative sensory testing (QST), nerve conduction tests, and biopsy are unable to detect subclinical changes, and do not consistently correlate with severity of patients' symptoms and functional impairment. This study aims to determine the utility of the LDI (laser Doppler imager) FLARE technique in the diagnosis of CIPN and whether it correlates with symptom severity.

A randomised phase 2 trial of dexamethasone versus prednisolone in castration-resistant prostate cancer.

Background: Prednisolone is widely used as secondary hormonal treatment for castration-resistant prostate cancer (CRPC). We hypothesised that dexamethasone, another corticosteroid, is more active.

Objective: To compare the activity of prednisolone and dexamethasone in CRPC.

Lobular neoplasia of the breast.

Lobular neoplasia is increasingly being detected, probably due to the widespread screening for breast malignancies. The understanding of lobular neoplasia is undergoing a paradigm shift, from being considered a predictor of recurrence to being considered a pre-invasive lesion, based on molecular studies suggesting a clonal link with invasive lobular cancer. The management of patients diagnosed to have lobular neoplasia is in evolution, with the increasing need for risk stratification and hence the necessity to identify this entity separately as either lobular carcinoma in-situ and atypical lobular hyperplasia.

Development of the European Organisation for Research and Treatment of Cancer quality of life questionnaire module for older people with cancer: The EORTC QLQ-ELD15.

Background And Aim: There is a lack of instruments that focus on the specific health-related quality of life (HRQOL) issues that affect older people with cancer. The aim of this study was to develop a HRQOL questionnaire module to supplement the European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire, the EORTC QLQ-C30 for older (>70years) patients with cancer.

Methods: Phases 1-3 were conducted in seven countries following modified EORTC Quality of Life Group guidelines for module development.

Late solitary testicular metastasis from rectal cancer.

Isolated testicular metastasis from rectal cancer is rare. We describe the case of a patient who presented with a locally advanced rectal malignancy and underwent multimodality treatment with low anterior resection, postoperative radiotherapy and adjuvant chemotherapy. He developed a painless testicular nodule while on follow-up, five years after the diagnosis of primary rectal cancer.

Serum micronutrient and antioxidant levels at baseline and the natural history of men with localised prostate cancer on active surveillance.

The aim of this study was to determine whether serum concentrations of micronutrients, antioxidants and vitamins predict rate of disease progression in untreated, localised prostate cancer. Patients with localised prostatic adenocarcinoma on a prospective study of active surveillance underwent monitoring with serial PSA levels and repeat prostate biopsies. Disease progression was defined as either adverse histology on repeat biopsy (primary Gleason grade >or=4 or >50% positive cores of total) or radical treatment for PSA velocity >1 ng ml(-1) year(-1).

Triple-negative/basal-like breast cancer: clinical, pathologic and molecular features.

Review of the spectrum of breast cancer tumor subtypes, which include basal-like, triple-negative and BRCA1-positive tumors, suggest that they have overlapping clinical, pathologic and molecular features, which are different from endocrine responsive breast cancers. Although response to chemotherapy is high in the neoadjuvant setting, the overall prognosis of this subset of tumors remains poor. Gene-profiling studies of this heterogeneous subset have lead to a better understanding of the molecular pathology of these aggressive tumors and the identification of possible therapeutic targets.

Results of combined modality treatment for nasopharyngeal cancer.

Context: Radiotherapy is the cornerstone of treatment in nasopharyngeal cancer (NPC); the addition of chemotherapy has shown improved results.

Aims: To compare the results of concurrent chemoradiation with that of radiotherapy alone in NPC.

Materials And Methods: One hundred and ninety consecutive NPC patients, without distant metastasis, who reported to the institute from January 1992 to December 2001, received external-beam radiation to 66 Gy in 33 fractions.

Is electroglottography-based videostroboscopic assessment of post-laryngectomy prosthetic speech useful?

Objectives: To use an electroglottography (EGG)-based videostroboscopy tool to assess the anatomical and morphologic characteristics of the pharyngoesophageal (PE) segment in tracheoesophageal (TO) speakers.

Study Design: Cross-sectional cohort study.

Subjects: Fifty-two post-laryngectomy patients with no recurrence and using prosthetic (Blom-Singer) speech.

Primary Adult Renal Ewing's Sarcoma: A Rare Entity.

Background. Ewing's sarcoma of extraskeletal origin is uncommon and that is of primary renal origin in adults are rare. There is no consensus on the optimal management of Ewing's tumors of renal origin.

Late solitary skeletal metastasis to the patella from retinoblastoma.

Isolate metastasis to the patella is rare. A young girl treated with bilateral enucleation for retinoblastoma, reported 9 years later with solitary patellar metastasis. Treatment options for distant metastasis from retinoblastoma are not well defined but include combinations of chemotherapy, radiotherapy and surgery.

Primary Adenoid Cystic Carcinoma Presenting as an Orbital Apex Tumor.

Primary adenoid cystic carcinoma occurring in the orbital apex is rare. We present the clinical features of a patient who initially presented with the clinical and radiologic features of an orbital pseudotumor. He developed features of orbital apex syndrome and repeat imaging showed a tumor of the orbital apex with intracranial invasion.

Clinical implications of introducing a new PSA assay.

Background: A number of different prostate-specific antigen (PSA) assays are in common use. There has been little consideration of the possible clinical implications of interassay variation. The availability of two assays in the same laboratory provided an opportunity to audit the clinical implications of the interassay variation in PSA levels.

Prospective, longitudinal electroglottographic study of voice recovery following accelerated hypofractionated radiotherapy for T1/T2 larynx cancer.

Background And Purpose: To measure voice outcomes following accelerated hypofractionated radiotherapy for larynx cancer.

Materials And Methods: Twenty-five patients with T1/T2 glottic cancer underwent serial electroglottographic and acoustic analysis (sustained vowel/i/ and connected speech) before radiotherapy and 1, 6 and 12 months post-treatment. Twenty-five normal subjects served as a reference control population.
