RESUMEN

The Veterans Health Administration (VHA) has pioneered teleoncology to address access challenges faced by Veterans requiring cancer care. This ASCO Educational Book highlights the development of teleoncology programs within the VHA: the local VA Pittsburgh Healthcare System (VAPHS) Virtual Cancer Care Center, the National TeleOncology Program (NTO), and the regional Clinical Resource Hub (CRH) Oncology Program. These initiatives provide oncology care using a hub-and-spoke model, which centralizes expertise at hub sites and reaches Veterans at distant spoke sites through synchronous and asynchronous care. The deployment of these teleoncology programs has resulted in significant benefits, such as decreased travel for Veterans, high levels of patient satisfaction, and improved access to specialized treatments. Despite these advancements, disparities in teleoncology utilization and access to clinical trials persist. This educational manuscript highlights the successes and challenges of tele-oncology within the VHA, underscoring the critical role of telehealth in overcoming access barriers.

RESUMEN

The Veterans Health Administration system is one of the largest integrated health care providers in the United States, delivering medical care to > 9 million veterans. Barriers to delivering efficient health care include geographical limitations as well as long wait times. Telehealth has been used as a solution by many different health care services. However, it has not been as widely used in cancer care. In 2018, the US Department of Veterans Affairs (VA) Pittsburgh Healthcare System expanded the use of telehealth to provide antineoplastic therapies to rural patients by creating a clinical video telehealth clinic of the Virtual Cancer Care Network. This allows oncologists located at the tertiary center to virtually deliver care to remote sites. The recent COVID-19 pandemic forced oncologists across the VA system to adopt telehealth to provide continuity of care. On the basis of our review and personal experience, we have outlined opportunities for telehealth to play a role in every step of the cancer care journey from diagnosis to therapy to surveillance to clinical trials for medical, surgical, and radiation oncology. There are many advantages, such as decreased travel time and potential cost savings; however, there continues to be challenges with veterans having access to devices and the Internet as well as understanding how to use telehealth equipment. The lessons learned from this assessment of the VA telehealth system for cancer care can be adopted and integrated into other health systems. In the future, there needs to be evaluation of how telehealth can be further incorporated into oncology, satisfaction of veterans using telehealth services, overcoming telehealth barriers, and defining metrics of success.

RESUMEN

We report a rare case of metastatic renal cell carcinoma (RCC) in a patient who developed rhabdomyolysis while on sunitinib. He was admitted to the hospital due to muscle weakness, fatigue, poor oral intake, and difficulty swallowing in March 2017. He was found to have pancytopenia, liver failure, kidney failure, high uric acid, and increased creatine phosphokinase of more than 5000. He quickly developed lactic acidosis and acute respiratory failure. He was transferred to the ICU, but his condition declined rapidly. He died 3 days later. In this article we discussed about sunitinib-mediated inhibition of adenosine monophosphate kinase (AMPK) as a possible pathophysiology of rhabdomyolysis. Our case is the third sunitinib-induced rhabdomyolysis reported in the literature.

RESUMEN

BACKGROUND: Dysfunctional mitochondrial processes limit malignant cells ability to use energy from fatty acids and ketones. Animal studies using ketogenic diets for cancer show encouraging results. We tested the diet's safety and feasibility in cancer patients across a broad variety of solid tumors. METHODS: We recruited 17 advanced cancer patients who were not on chemotherapy. They consumed 20 to 40 g of carbohydrates daily with evaluations performed weekly until week 4, then every 4 weeks until 16 weeks. Quality of life questionnaires monitored for tolerability and compliance. Positron emission/computerized tomography was ordered at baseline, 4,8 and 16 weeks. Student t-testing evaluated differences between baseline and last visit scores for quality of life, weight, body mass index, and serum parameters. Correlations between weight loss and serum ketones, glucose, lipids and creatinine were done. Two-tailed unpaired t-testing of the mean weight loss compared responders against non-responders. RESULTS: Eleven out of seventeen enrolled patients were evaluable. Mean age was 65+/- 11.7 years, weight 203 +/- 4.98 lbs. (92 ± 2.3 kgs.) and previous treatment failures was 1.7, +/- 0.97. All lost significant weight with hematologic, biochemical and lipid tests remaining stable. Quality of life scores slightly improved. At 4,8 and 16 weeks, six (54.5 %), five (45.4 %) and four (36 %) patients were stable or improved. We observed no correlations between serum glucose, ketones or lipids. Clinical response did not correlate with ketosis or glycemia. Responders (stable disease or partial responders) lost statistically more weight than non-responders. Dietary compliance was difficult. Only three patients continued dieting past 16 weeks. Out of these, two patients developed brain metastases and were on steroids. They survived 80 and 116 weeks respectively. The third patient underwent residual tumor resection and has no disease at 131 weeks. CONCLUSIONS: Modified Atkins diets are safe and feasible in advanced cancer. Quality of life was preserved. Patients who lost at least 10 % of their body weight responded the best. Steroid intake affected optimal ketone and glucose levels. Despite this, survival improved in some melanoma and lung cancer patients. Further studies are recommended. TRIAL REGISTRATION: Clinicaltrials.gov NCT01716468. Registered on September 18, 2012.

RESUMEN

Approximately 1 in 14 men and women during their lifetime will be diagnosed with lung cancer, which is the leading cause of cancer-related mortality in the world. As of January 1, 2008, there were about 373,500 men and women living with lung cancer in the United States. Fewer than 60,000 of these are estimated to be alive by January 2013, reflecting a poor overall 5-year relative survival rate of under 16 %. With metastatic cancer, the overall 5-year survival is meager 4 %. On the other hand, the overall five-year survival is over 50 % when the cancer is still in the localized stage. However, unfortunately, more than half of cases of lung cancer are diagnosed at an advanced stage Howlader et al. (2010). Cancer metastasis, the single most critical prognostic factor, is still poorly understood and a highly complex phenomenon. The most common sites of lung cancer metastasis are the lymph nodes, liver, adrenals, brain and bones. The gastrointestinal (GI) tract is an exceptionally rare site of metastasis; with only a handful of cases reported in the literature Centeno et al. (Lung Cancer, 18: 101-105, 1997); Hirasaki et al. (World J Gastroenterol, 14: 5481-5483, 2008); Carr and Boulos (Br J Surg, 83: 647, 1996); Otera et al. (Eur Respir Rev, 19: 248-252, 2010); Antler et al. (Cancer, 49: 170-172, 1982); Fujiwara et al. (Gen Thorac Cardiovasc Surg, 59: 748-752, 2011); Stinchcombe et al. (J Clin Oncol, 24: 4939-4940, 2006); John et al. (J Postgrad Med, 48: 199-200, 2002); Carroll and Rajesh (Eur J Cardiothorac Surg, 19: 719-720, 2001); Brown et al. (Dis Colon Rectum, 23: 343-345, 1980). We report three cases of non-small cell (squamous cell) lung cancer with GI tract metastasis-two in the colon and one in the jejunum. Then we present a review of literature exploring various theories of metastasis, as an attempt to understand the reason of preferential tumor metastasis.
