Opioids are the gold standard for the treatment of cancer-related pain. Preclinical studies have associated opioids with cancer progression and overall survival. In mice models, opioids have been shown to possess pro-tumor activity secondary to immunosuppression, migration of tumor cells, increased activity of vascular endothelial growth factor receptors, and angiogenesis leading to tumor progression. ⋯ The survival in these advanced cancer patients taking opioids may be more likely to be associated with cancer progression and not the opioid use. Adequate treatment of cancer pain has the potential to improve quality of life and performance status, highlighting the importance of continuing to use opioids to manage pain efficiently. More research is clearly needed.

Treatment-related cardiotoxicity remains a significant concern for breast cancer patients undergoing cancer treatment and extends into the survivorship period, with adverse cardiovascular (CV) outcomes further compounded by the presence of pre-existing CV disease or traditional CV risk factors. Awareness of the cardiotoxicity profiles of contemporary breast cancer treatments and optimization of CV risk factors are crucial in mitigating cardiotoxicity risk. ⋯ Mismatch between baseline cardiotoxicity risk and intensity of cardiotoxicity surveillance can lead to unnecessary downstream testing, increased healthcare expenditure, and interruption or discontinuation of potentially life-saving treatment. Efforts to identify early imaging and/or circulating biomarkers of cardiotoxicity and develop effective management strategies are needed to optimize the CV and cancer outcomes of breast cancer survivors.

ReviewOpioid Prescribing in an Opioid Crisis: What Basic Skills Should an Oncologist Have Regarding Opioid Therapy?
Although clinical evidence supports the use of opioids for cancer-related pain, doing so amidst the current opioid crisis remains a challenge. A proportion of opioid-related deaths in the USA are attributable to prescription opioids, which implicates health care providers as one of the major contributors. It is therefore even more important now for all clinicians to follow safe and effective opioid prescribing practices. ⋯ When aberrant behavior is detected, the clinician will need to openly discuss the issue and its possible implications. Oncologists may then implement measures such as limiting the dose and quantity of opioids prescribed, shortening interval between follow-ups for refills to allow for increased monitoring, setting boundaries/limitations, weaning off opioid analgesics, or/and referring to a pain or palliative medicine or drug addiction expert for co-management when necessary. These efforts may aid oncologists in safely managing cancer pain in the environment of national opioid crisis.

ReviewThe Role of Angiogenesis Inhibitors in the Era of Immune Checkpoint Inhibitors and Targeted Therapy in Metastatic Non-Small Cell Lung Cancer.
The treatment of advanced non-small cell lung cancer (NSCLC) has evolved to include targeted therapy, immunotherapy as well as chemotherapy for selected patients in the first-line setting. Angiogenesis inhibitors have been used in combination with chemotherapy in the first-line and maintenance settings providing improved progression-free survival (PFS) and objective response rate (ORR), as well as overall survival (OS) in selected studies. Biologic rationale exists for combining anti-angiogenic agents with immunotherapy and targeted kinase inhibitors (TKIs). ⋯ The combination of EGFR inhibitors plus vascular endothelial growth factor (VEGF) inhibitors in the EGFR mutation-positive population has demonstrated substantial improvements in response and PFS; however, given the higher toxicity and lack of survival benefit to date, combination therapy in this group should be used with caution. At the present time, use of bevacizumab can be recommended with atezolizumab and chemotherapy for the first-line treatment of non-squamous NSCLC patients. Data with other checkpoint inhibitors and anti-angiogenics are too early to make firm recommendations regarding their use.

ReviewNovel Surgical Strategies in the Treatment of Gynecological Malignancies.
The main advancement in the surgical treatment of early cervical cancer has been a de-escalation in the radical surgical approach of early stage disease. Similarly, sentinel lymph node detection with cervical tracer injection can be performed alone in microscopic tumors (stage IA) while additional lymphadenectomy is still performed in macroscopic tumors (IB1 and IIA). Parametrial resection has been progressively reduced in tumors less than 2 cm, and simple procedures, conservative (trachelectomy) or not (simple hysterectomy), are currently being evaluated in several phase III trials. ⋯ HIPEC after interval debulking surgery in patients undergoing complete cytoreduction is an intriguing new option. Patients within the first recurrence of ovarian cancer, with score AGO-positive, benefit from a second complete cytoreductive surgery followed by chemotherapy. Ovarian cancer survival rates are higher in specialized high-volume centers, and thus cases should be centralized and quality indicators used.
