Metastatic Pancreatic Cancer: Where Are We?

Pancreatic cancer is one of the most lethal neoplasms worldwide; it is aggressive in nature and has a poor prognosis. The overall survival rate for pancreatic cancer is low. Most patients present non-specific symptoms in the advanced stages, which generally leads to late diagnosis, at which point there is no option for curative surgery. The treatment of metastatic pancreatic cancer includes systemic therapy, in some cases radiotherapy, and more recently, molecular targeted therapies, which can positively impact cancer control and improve quality of life. This review provides an overview of the molecular landscape of pancreatic cancer based on the most recent literature, as well as current treatment options for patients with metastatic pancreatic cancer.

Thyroid cancer in women of reproductive age: Key issues for the clinical team.

Women who are fertile experience a significant burden from thyroid cancer. In reality, delaying childbirth is the current trend in maternity. Women who have thyroid cancer may later want to get pregnant after it has been treated, which presents a multidisciplinary issue for their doctors. A variety of specialists are frequently involved in the treatment of thyroid cancer. This review aims to address the key elements of the strategy and places special emphasis on the significance of fertility in women with thyroid cancer diagnosis and remission. We will cover topics including the role of thyroid hormones in pregnancy and fertility.

Painful shoulder and scapula as initial presentation of advanced lung adenocarcinoma.

Lung adenocarcinoma is a common cancer; even though it has a strong association with previous smoking, there has been described nonsmokers-related cases. Symptoms varies from asymptomatic to hemoptysis or pleural effusion. We describe a case of a patient who presented with painful scapula as primary manifestation of advanced pulmonary malignancy.

Sexual dysfunction as a challenge in treated breast cancer: in-depth analysis and risk assessment to improve individual outcomes.

The increasing number of breast cancer survivors has led to a greater emphasis on issues related to quality of life (QoL). Up to 75% of women treated for breast cancer (BC) report sexual disorders. However, most oncologists are not trained to recognize which patients are at high-risk of developing sexual disorders. Female sexual dysfunction (FSD) is common in patients with BC; we found that patients without FSD prior to BC treatment are at risk of developing FSD after treatment. Treatment of early BC relies on the combination of chemotherapy, surgery, and radiation therapy. All these treatments have side effects or sequelae identified as high-risk factors for the development of FSD. The choice of less toxic treatments in each modality could reduce the risk of FSD in some cases, without affecting the risk of recurrence or effectiveness. A comprehensive approach of BC must consider FSD as a determinant factor of QoL in survivors.

Endometrial carcinosarcoma: a poor prognosis debut with favourable therapeutic outcome.

Endometrial carcinosarcoma (ECS) is a rare, highly aggressive disease characterised by a biphasic growth of malignant epithelial (carcinomatous) and mesenchymal (sarcomatous) components. Clinically, it cannot be distinguished from endometrial carcinoma or uterine sarcoma. The definitive diagnosis can only be made based on histological examination and immunohistochemistry. To date, there aren't standardised treatment protocols for its management. We report a case of a 73-year-old patient who presented postmenopausal abnormal uterine bleeding and was diagnosed with ECS. A non-conventional treatment approach was conducted with favourable oncological outcomes.

Asbestos and cancer in Latin America and the Caribbean: we may have won some battles, but definitely not the war.

Only six countries have banned the industrial use of asbestos in Latin America and the Caribbean. In fact, the industrial use of asbestos appears to be growing in this region. Asbestos is one of the most dangerous natural substances in the world, it is contained in several types of rocks (such as serpentinites, mafic and ultramafic rocks) but fibers can be released to the atmosphere both by natural and antropogenic sources. Six countries have banned the industrial use of asbestos in this region, we expected that laws established before 2007 would be less adherent to the 2007 WHO/ILO recommendations. In contrast, the Chilean law of 2001 is one of those that most adheres to international recommendations along with the Colombian law of 2021. Which means that the newest laws are not necessarily the strongest. This article aims to draw a regional overview of the laws against asbestos production in Latin America and the Caribbean, highlighting the strengths and weaknesses of each national policy. We recommend that countries that have already banned asbestos consider updating and strengthening their existing laws and develop clinical guidelines for the management, monitoring, and rehabilitation of asbestos-related diseases. The challenge of asbestos goes far beyond a prohibition law.

Improving access to high-cost cancer drugs in Latin America: Much to be done.

Lack of access to high-cost medications is a complex issue at the intersection of economics, medicine, politics, and ethics, and it poses a significant threat to global health care. The problem is even more significant in low- and middle-income countries, such as those in Latin America, where governments and individuals struggle to pay for products that are priced at several times the level of their per capita gross domestic product. In this review, we examine the determinants for increasing drug costs and how Latin American countries face this burgeoning crisis. We emphasize that a number of opportunities and strategies to reduce costs and improve access exist and should be identified and implemented, ideally within a regional approach with multiple stakeholders involved and based on systematic and transparent cost-effectiveness analyses.

Current and emerging therapies of HER2-positive metastatic breast cancer.

The HER2 receptor as measured by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) is overexpressed in 15-20% of all breast cancers and traditionally represents adverse biology and a guarded prognosis, particularly in HER2 positive metastatic breast cancer (MBC). Trastuzumab and newer anti-HER2 targeting agents have significantly improved the clinical outcomes of patients with HER2 positive MBC. The development of new techniques has led to discovery of promising biomarkers that can lead to more precise selection of patients for anti-HER2 therapies. This paper summarizes these new biomarkers, useful in selecting patients for treatment with new and emerging therapies for HER2 positive MBC. Emerging next generation sequencing techniques have truly changed the landscape of HER2 positive MBC. Deployment of multiple anti-HER2 therapies in combination is a strategy which has yielded additive or even synergistic effects and has led to markedly improved patient outcomes in HER2+ MBC. In the future, in order to further improve the treatment of these patients and to reduce toxicities, we need to improve our understanding of HER2-dependent pathways and their function, and to develop further treatment combinations while optimizing selection of patients by identifying new biomarkers. The results of prospective studies using CTCs, cDNA and other promising new biomarkers are awaited with great interest.

Patterns of care, predictors and outcomes of chemotherapy for ovarian carcinosarcoma: A National Cancer Database analysis.

OBJECTIVE: The aim of this study is to determine if outcomes of patients with ovarian carcinosarcoma (OCS) differ from those of women with high-grade papillary serous ovarian carcinoma (HG-PSOC) when compared by stage and treatment modalities. METHODS: The National Cancer Database was queried to identify patients with OCS and HG-PSOC diagnosed between 2003 and 2011. Demographic and clinical data were compared, and the impact of tumor histology on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model. RESULTS: The final study group consisted of 45,153 women. 2886 (6.39%) had OCS and 42,267 (93.61%) had HG-PSOC. The mean age at diagnosis was 65.43 (±12.21) years for women with OCS and 61.52 (±12.6) years for HG-PSOC (P<0.001). African-American women had higher rate of OCS relative to white non-hispanic women (7.84% vs. 6.37%; P=0.002). Overall, women with OCS had a worse five-year survival rate, 26.63% [95% Confidence Interval (CI)=24.86%-28.53%] vs. 43.61% (95% CI=43.07%-44.17%). This difference persisted for each FIGO disease stage I-IV, with five-year survival consistently worse for women with OCS compared to those with HG-PSOC. Over the entire study period and after adjusting for histology, age, period of diagnosis, SEER registry, marital status, stage, surgery, radiotherapy, and lymph node dissection, carcinosarcoma histology was associated with decreased survival. CONCLUSION: OCS is associated with a poor prognosis compared to HG-PSOC. This difference was noted across all FIGO stages.
