Early Access to Electronic Health Records May Influence the Patient Experience.

In a recent Hot Topics column, Mehmet Sitki Copur, MD, FACP, et al discussed the pros and cons of patients receiving test results early through electronic medical records.

Complete Pathologic Response to Neoadjuvant Chemoimmunotherapy and Oxaliplatin-Induced Fever Associated With IL-6 Release in a Patient With Locally Advanced Colon Cancer

Neoadjuvant systemic therapy is a preferred treatment approach for a number of tumor types due to many potential advantages over upfront surgery, including tumor downstaging, early treatment of micrometastatic disease, and providing an in vivo test of tumor biology. For colon cancer, current standard of care is upfront surgery followed by adjuvant systemic therapy in high-risk patients. Concerns about inaccurate radiological staging and tumor progression during preoperative treatment, as well the lack of randomized data demonstrating benefit, are among the reasons for the limited use of neoadjuvant therapy in this disease. Locally advanced colon cancer, defined as primary colon cancer with direct invasion into the adjacent structures or extensive regional lymph node involvement, is not always amenable to pathological complete resection, and when attempted it comes with high incidence of postoperative morbidity and mortality because of the required multivisceral resection. Clinical trials of neoadjuvant chemotherapy for colon cancer to date have been promising with downstaging of disease and higher rates of R0 resection. Here, we report a case of a patient with locally advanced, unresectable, mismatch repair deficient sigmoid colon cancer who was treated with neoadjuvant chemoimmunotherapy followed by surgical resection leading to a complete pathologic response after preoperative systemic chemoimmunotherapy.

Messenger RNA Vaccines: Beckoning of a New Era in Cancer Immunotherapy.

Messenger RNA (mRNA) vaccines are a relatively new class of vaccines. They combine the potential of mRNA to encode for almost any protein with an excellent safety profile and a flexible production process. During the last decade, the mRNA vaccine approach has been increasingly recognized and viewed as a versatile tool for the development of new innovative therapeutics not only in infectious disease settings but also in cancer. mRNA vaccines traditionally consist of a messenger RNA synthesized by in vitro transcription using a bacteriophage RNA polymerase and a template DNA that encodes the antigen(s) of interest. Once administered and internalized by host cells, the mRNA transcripts are translated directly in the cytoplasm of the cell. The resulting antigens are presented to the immune system cells to stimulate an immune response. Dendritic cells (DCs) can be utilized as a carrier by delivering tumor-associated antigen mRNAs or total tumor RNA to their cytoplasm; then, the mRNA-loaded DCs can be delivered to the host to elicit a specific immune response. Recently, 2 mRNA vaccines were approved for the first time for human use-to prevent COVID-19 infection-bringing excitement for the future possibilities of this approach for cancer immunotherapy as well as for preventing other infectious diseases.

A 65-Year-Old Man With Back Pain and Imaging Findings of Spinal Cord Compression.

Spinal cord compression is a potentially devastating consequence of cancer. Early recognition of the signs and symptoms permit diagnosis prior to the development of irreversible neurological damage. This complication occurs in 5% to 10% of patients with malignancy, often at the end stages of the patient's illness; however, it can be the presenting manifestation of malignancy in up to 23% of patients. With the advances in surgical, radiation, and medical oncology approaches, the outcomes of patients with malignant spinal cord compression continue to improve. We discuss the case of a previously healthy man, aged 65 years, who presented with back pain and large T8 spinal mass, leading to a diagnosis of multiple myeloma with spinal cord compromise.

A 64-Year-Old Man With Germline BRCA2-Mutated Breast Cancer: Known and Unknown Aspects of Male Breast Cancer.

Male breast cancer is a rather uncommon and understudied disease. It accounts for less than 1% of all breast cancers, but in recent decades its frequency has been on the rise. Clinical trials of breast cancer have traditionally excluded men. Due to the lack of large-scale prospective studies, most published data come from single-institution, small-cohort studies, and treatment recommendations are based on the extrapolation of data from clinical trials enrolling only women. Although to some extent etiology, diagnosis, and treatment characteristics can be similar, male breast cancer exhibits some distinct features. Men tend to be diagnosed with breast cancer at an older age and at a more advanced stage. A better understanding of the biologic features, clinically relevant differences, effective treatments, and outcomes of male breast cancer is crucial to appropriately manage these patients. We present a male breast cancer case with a germline BRCA2 mutation and discuss the epidemiologic, pathologic, and clinical characteristics along with treatment and follow-up recommendations in view of our recent understanding of this disease.

Mucinous Adenocarcinoma of the Appendix With Histologic Response to Neoadjuvant Chemotherapy: Review of Histologic and Clinical Spectrum of Epithelial Neoplastic Mucinous Lesions of the Appendix.

Appendiceal mucinous neoplasms are a rare and heterogeneous group of diseases with challenging clinical management decisions. They account for less than 1% of all cancers but their incidence is on the rise. Treatment is based on their stage and histology. Appendiceal neoplasms frequently metastasize inside the abdomen; this leads to tumor cell growth in the abdominal cavity, known as peritoneal carcinomatosis, and buildup of mucinous material, known as pseudomyxoma peritonei. While low-grade, early-stage tumors can be effectively treated with limited surgical resection, patients with low-grade, advanced-stage disease require peritoneal debulking and hyperthermic intraperitoneal chemotherapy. Therapeutic options for high-grade, advanced-stage mucinous tumors of the appendix have not been well established. Debulking surgery with hyperthermic intraperitoneal chemotherapy preceded and/or followed by systemic chemotherapy has been utilized based on some prospective but not randomized data. We present a case of mucinous adenocarcinoma of the appendix treated with neoadjuvant chemotherapy followed by cytoreductive surgery/hyperthermic intraperitoneal chemotherapy and adjuvant chemotherapy. Preoperative chemotherapy provided a favorable histologic response by converting initial mucinous appendiceal adenocarcinoma histology to a high-grade mucinous appendiceal neoplasm.

Gastrointestinal Cancer Presentations Relevant to Clinical Practice.

The 2020 American Society of Clinical Oncology Virtual Scientific Program delivered many practice-influencing presentations. Here are some of the most notable research results in the field of gastrointestinal cancer that may guide oncologists in their day-today work.

76-Year-Old Woman With a Bluish-Purple Lump in her Left Upper Medial Leg.

A woman, aged 76 years, presented with a bluish-purple lump in her mid- to upper medial left thigh. It started initially as a flat rash, and over a 2-month period, it turned into a mass measuring 2.5 cm by 3.1 cm. Work-up, including a PET-CT scan, showed the soft tissue mass on the inner thigh to have a Standardized Uptake Value of 4; there were no other sites of disease. A biopsy of the lesion was performed.

79-year Old Man on Nivolumab with Itchy Erythematous Patches.

A 79-year-old white man presented with an ulcerated chest wall lesion developing from an existing mole. After definitive surgery, it proved to be a malignant melanoma and staged as T4N1M0. He received 1 year of adjuvant therapy with nivolumab. Starting on the last month of adjuvant nivolumab treatment, he developed itchy erythematous patches on his left posterior shoulder that spread over his trunk, arms, and thighs.

Locally Advanced Rectal Cancer, What is the Standard of Care?

Colorectal carcinoma is the second leading cause of cancer-related deaths in the United States, with rectal cancer accounting for approximately one-third of newly diagnosed cases. A comprehensive trimodality approach involving neoadjuvant chemoradiotherapy, total mesorectal excision, and systemic chemotherapy has been the standard of care for medically operable patients with nonmetastatic, locally advanced rectal cancer. Despite a marked reduction in local recurrence rates with good local control, systemic recurrence rates of as high as 35% constitute the leading cause of death in this population. This has led to increasing interest in neoadjuvant systemic therapy before or after neoadjuvant chemoradiation a new approach called total neoadjuvant therapy. This case study will review the current status of clinical stage II or III locally advanced rectal cancer (T3/4, N0, or node-positive) treatment regarding neoadjuvant therapy.

Recurrent Small Cell Carcinoma of the Lung With Cutaneous Metastasis in Breast.

Lung cancer remains the leading cause of cancer-related deaths and the second leading cause of new cancer cases in the United States. Although more commonly involving hilar nodes, the liver, adrenal glands, bones, and the brain, lung cancer can metastasize to almost any organ. Metastases, although rare in the skin may be the first sign of a lung cancer or cutaneous metastases may present as a sign of recurrent disease. The incidence of cutaneous metastases from lung cancer has been reported in approximately 1% to 12 % of cases and was associated with poor prognosis. Although cutaneous metastasis from small cell lung cancer is a rare occurrence, cutaneous metastasis involving the breast is even less common. Here, we present a case of recurrent small cell lung cancer presenting with a firm purplish cutaneous metastatic nodule in the right breast.

Recurrent EGFR-Mutated Non-Small Cell Lung Cancer Discovered by Abnormal Mammogram: Adjuvant/Frontline Metastatic Management Options.

Breast metastasis from extramammary malignancy is rare, with a reported incidence rate of 0.4% to 1.3% in the published literature. The primary malignancies that most commonly metastasize to the breast are leukemia, lymphoma, and malignant melanoma. Here, we report a very rare case of metastatic EGFR-mutated non-small cell lung cancer (NSCLC) in the breast detected by screening mammography. The patient had initially been diagnosed with a clinical stage IIIA NSCLC and had been treated with neoadjuvant chemoradiation followed by curative-intent surgery. Several interesting aspects of the case, along with a discussion of evolving adjuvant and frontline metastatic management options in EGFR-mutated NSCLC, will be presented.

Synchronous Bilateral Lung Cancer With Discordant Histology.

Synchronous multiple primary lung cancer (SMPLC) is a rare occurrence affecting 0.5% to 2% of patients with lung cancer. Synchronous discordant histology with small cell and non-small cell lung carcinoma is an even less common entity. There have been several presentations of synchronous or metachronous multiple primary lung cancers in the literature. However, reports discussing treatment options and prognosis in patients with SMPLC of discordant histology with small cell and non-small cell carcinoma in the same patient are scarce. We report a case of SMPLC presenting with a limited stage left upper lobe small cell lung cancer and an operable right upper lobe non-small cell lung adenocarcinoma. Diagnostic, surgical, and medical treatment options for the patient along with a review of SMPLC topics are presented.

Pancreatic Neuroendocrine Tumor With Humoral Hypercalcemia and High Tumor PD-L1 Score.

Pancreatic neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms. They can be functioning tumors with secretion of a variety of peptide hormones, or nonfunctioning tumors with metastases to the liver at the time of diagnosis. Well-differentiated tumors tend to be slow-growing and characterized by low tumor mutational burden (TMB) and lower propensity to express PD-L1. Hypercalcemia due to malignancy can occur in about 20% to 30% of patients with cancer. The secretion of parathyroid hormone-related protein (PTH-rP) is among the causes of malignant hypercalcemia and has seldom been associated with hypercalcemia of NETs. Although the therapeutic landscape for neuroendocrine neoplasms has evolved substantially over the past decade, the role of immunotherapy has not yet been completely explored in this group of patients. We present a rare case of a metastatic pancreatic NET with high TMB, high PD-L1 tumor proportion score, and high PTH-rP related hypercalcemia.

Hereditary vs Familial Pancreatic Cancer: Associated Genetic Syndromes and Clinical Perspective.

Pancreatic ductal adenocarcinoma (PDAC) is a disease marked by high rates of mortality; it is mostly incurable at the time of diagnosis. Only about 7% of patients survive 5 years after diagnosis. Diagnosis at a late stage and rapid progression with minimal response to available treatments are the main reasons for this poor outcome. It is crucial to identify individuals at high risk of developing PDAC so preventive and early detection measures can be employed. Approximately 10% to 15% of PDAC cases have a hereditary or familial basis. In the majority of PDAC cases, no main causative gene has been identified, but several known germline pathogenic mutations have been shown to be related to an increased risk of this cancer. The presence of 2 or more patients with pancreatic cancer within the circle of first-degree relatives, without the presence of a causative germline mutation, is defined as familial pancreatic cancer; this accounts for 4% to 10% of PDAC. Based on the growing evidence supporting the benefit of germline genetic testing in patients with PDAC, both the American Society of Clinical Oncology and the National Comprehensive Cancer Network recently updated their guidelines to include recommendations around genetic testing for patients with pancreatic cancer. However, there is no general consensus on the group of patients and individuals who should be studied and screened. We present a demonstrative case and review the available data on hereditary and familial PDAC.

Locally Advanced Gastrointestinal Stromal Tumor in a 33-Year-Old Woman Seeking to Conceive.

Gastrointestinal stromal tumors (GISTs) are rare neoplasms of the gastrointestinal tract. They commonly present with nonspecific symptoms and thus are often discovered incidentally. They are best identified by CT scan, and most stain positive for CD117 (C-Kit), CD34, and/or DOG-1. Several risk stratification classification systems have been developed based on tumor size, mitotic rate, location, and perforation. Traditional chemotherapy and radiation therapy have been very ineffective, making surgery the mainstay of treatment. The discovery of mutations associated with these tumors has revolutionized the treatment approach. Imatinib mesylate, a selective tyrosine kinase receptor inhibitor, used as adjuvant or neoadjuvant therapy, has greatly improved the morbidity and mortality associated with GISTs. As the survival of patients has increased with the long-term use of targeted therapies, quality-of-life issues now have become much more relevant and have come to the forefront of care. We present a young woman who was successfully treated for GIST but now faces associated long-term adverse effects of imatinib, including the challenge of preserving fertility and the potential for childbearing.

Burnout in Oncology.

Burnout is defined as an occupational-related syndrome characterized by physical and emotional exhaustion, cynicism/depersonalization, and low sense of professional accomplishment. Multiple oncology-specific risk factors are associated with an increased susceptibility for the development of burnout. On a daily basis, oncologists are faced with life and death decisions and grieving much more frequently than are physicians in other specialties. Continuous exposure to fatal illnesses with limited success in curing them, exceedingly long work hours with more administrative time demands, limited autonomy over daily responsibilities, endless electronic documentation requirements, and a shifting medical landscape seem to be making oncologists more vulnerable to suffering from burnout. Evidence suggests that burnout can impact quality of care in a variety of ways and have potentially profound personal implications. In this review, the definition, prevalence, causes, and management of oncologist burnout are analyzed. Steps oncologists can take to promote personal well-being and professional satisfaction are also explored.

Immunotherapy in Colorectal Cancer.

Colorectal cancer (CRC) is the third leading cause of cancer deaths, with only 15% of patients surviving 5 years in the metastatic setting. Recent exciting developments in cancer immunotherapy, which involves priming the host's natural immune defenses to recognize, target, and destroy cancer cells effectively, have brought some glimpse of hope in fighting this deadly disease. Although CRC has been shown to evade immune detection like many other cancers do, immunotherapy has been noted to produce some very impressive results in a select group of patients. Patients with mismatch repair-deficient and microsatellite instability-high type CRC have benefited most from recent immunotherapy approaches, leading to US Food and Drug Administration approval of new immunotherapeutic agents in recurrent refractory metastatic disease. Research continues to explore and hopefully define the role of immunotherapy in CRC as single-agent therapy or in combination with other agents in neoadjuvant, adjuvant, and first-line metastatic setting, and to find the optimal combination and sequencing of this new therapeutic approach. One of the most challenging tasks is to find ways to expand the use of immunotherapy to not only a select group of CRC patients but also to all patients with this disease. This article will provide a practical concise overview of the current landscape of immunotherapy in CRC for the practicing oncologist along with a representative case presentation from our community oncology practice.
