The testis is one of the most abundant sources of microtubule networks. These networks include mitotic and meiotic spindles, the spermatid manchette and axoneme, and the Sertoli cell cytoskeleton. Microtubules are composed of alpha- and beta-tubulin subunits that are polymerized and stabilized by a variety of microtubule-associated proteins (MAPs)....

Gastric cancer is a common disease with a high mortality. This article aims to outline the management options for patients with gastric cancer. The mainstay of curative treatment remains surgical resection. The management of early stage gastric cancer is complex with proven benefit of both pre-operative chemotherapy and postoperative chemo-radiothe...

Background Immunotherapy has emerged as a standard treatment for deficient mismatch repair (dMMR) metastatic colorectal cancer (mCRC). Pembrolizumab became widely available as a first‐line (1L) option in Australia following the Pharmaceutical Benefits Scheme (PBS) listing in August 2021. The uptake of new treatment options can be lengthy. Methods...

e15569 Background: Keynote 177 was a practice changing study, with pembrolizumab versus dealers’ choice chemotherapy +/- biologic significantly improving progression free survival in patients (pts) with previously untreated deficient mismatch repair (dMMR) metastatic colorectal cancer (mCRC). A high rate (29.4%) of pembrolizumab treated pts had sto...

12 Background: Adjuvant chemotherapy (CT) following neoadjuvant chemoradiation and surgery for locally advanced rectal cancer (LARC) is widely adopted, despite uncertain survival benefit. Circulating tumor DNA (ctDNA) detection after surgery has been shown to be a strong prognostic marker in localized colorectal cancer and potentially could inform...

A woman in her 50s with metastatic hormone receptor positive breast cancer developed rhabdomyolysis and subsequent acute kidney injury while on a combination of ribociclib and rosuvastatin therapy. She had been taking both medications long term and had recently recommenced her ribociclib at her usual dose after a routine 1 week break. Cyclin-depend...

LBA100 Background: The role of adjuvant chemotherapy (CT) in stage II colon cancer continues to be debated. The presence of circulating tumor DNA (ctDNA) after surgery predicts very poor recurrence-free survival (RFS), while its absence predicts a low recurrence risk. For ctDNA-positive cases the benefit of adjuvant CT is unknown. DYNAMIC was desig...

Background: The role of adjuvant chemotherapy in stage II colon cancer continues to be debated. The presence of circulating tumor DNA (ctDNA) after surgery predicts very poor recurrence-free survival, whereas its absence predicts a low risk of recurrence. The benefit of adjuvant chemotherapy for ctDNA-positive patients is not well understood. Met...

Background: RESILIENT (NCT03088813) is a phase 2/3 study assessing the safety, tolerability, and efficacy of liposomal irinotecan monotherapy in patients with small cell lung cancer and disease progression on/after first-line platinum-based therapy. Here, we present results from RESILIENT part 1. Methods: This open-label, single-arm, safety run-...

Background: This study: (i) assessed compliance with a consensus set of quality indicators (QIs) in pancreatic cancer (PC); and (ii) evaluated the association between compliance with these QIs and survival. Methods: Four years of data were collected for patients diagnosed with PC. Cox proportional hazards models were used to estimate hazard rati...

9069 Background: Most patients with extensive SCLC develop drug resistance to platinum-based 1L therapy or discontinue for other reasons, and second-line (2L) therapies are limited. RESILIENT (NCT03088813) is a two-part phase 2/3 study assessing the safety, tolerability and efficacy of 2L liposomal irinotecan monotherapy in adults with SCLC who pro...

TPS9081 Background: Although small cell lung cancer (SCLC) is often sensitive to established first-line therapies, many patients relapse and develop drug resistance, and second-line therapies are limited. RESILIENT (NCT03088813) is a two-part phase 2/3 study assessing the safety, tolerability, and efficacy of liposomal irinotecan monotherapy in pat...

Abstract BACKGROUND: Patients who are immunocompromised because of malignancy have an increased risk of herpes zoster and herpes zoster-related complications. We aimed to investigate the efficacy and safety of an inactivated varicella zoster virus (VZV) vaccine for herpes zoster prevention in patients with solid tumour or haematological malignancie...

8562 Background: Nal-IRI is investigated as monotherapy in patients with SCLC who progressed on or after platinum regimen. The RESILIENT study is a Part 1 study of a Phase 2/3 trial to assess safety, tolerability, and efficacy of Irinotecan Liposome Injection in patients with SCLC. Methods: Nal-IRI is evaluated in patients ≥18 yrs with advanced SCL...

Detection of circulating tumor DNA (ctDNA) after resection of stage II colon cancer may identify patients at the highest risk of recurrence and help inform adjuvant treatment decisions. We used massively parallel sequencing-based assays to evaluate the ability of ctDNA to detect minimal residual disease in 1046 plasma samples from a prospective coh...

Background: This study sought to understand the preferences of patients with cancer and the trade-offs between appointment attributes using discrete choice experiment (DCE). Methods and study design: Patients with cancer at 3 hospitals completed a self-administered DCE. Each scenario described 6 attributes: expertise of health care professionals...

"Cancer 2015" is a longitudinal and prospective cohort. It is a phased study whose aim was to pilot recruiting 1000 patients during phase 1 to establish the feasibility of providing a population-based genomics cohort. Newly diagnosed adult patients with solid cancers, with residual tumour material for molecular genomics testing, were recruited into...

Neoadjuvant chemotherapy for breast cancer allows response to be assessed depending on subtype, and to judge impact of response to therapy on progression-free survival (PFS). Methods: This study enrols women with breast tumours > 2cm and high likelihood of response, to receive Epirubicin 90mg/m2 and Cyclophosphamide 600mg/m2 Q3 weeks x 4 followed b...
