Developing national cancer survivorship standards to inform quality of care in the United States using a consensus approach.

PURPOSE: To develop United States (US) standards for survivorship care that informs (1) essential health system policy and process components and (2) evaluation of the quality of survivorship care. METHODS: The National Cancer Institute and the Department of Veterans Affairs led a review to identify indicators of quality cancer survivorship care in the domains of health system policy, process, and evaluation/assessment. A series of three virtual consensus meetings with survivorship care and research experts and advocates was conducted to rate the importance of the indicators and refine the top indicators. The final set of standards was developed, including ten indicators in each domain. RESULTS: Prioritized items were survivor-focused, including processes to both assess and manage physical, psychological, and social issues, and evaluation of patient outcomes and experiences. Specific indicators focused on developing a business model for sustaining survivorship care and collecting relevant business metrics (e.g., healthcare utilization, downstream revenue) to show value of survivorship care to health systems. CONCLUSIONS: The National Standards for Cancer Survivorship Care can be used by health systems to guide development of new survivorship care programs or services or to assess alignment and enhance services in existing survivorship programs. Given the variety of settings providing care to survivors, it is necessary for health systems to adapt these standards based on factors including age-specific needs, cancer types, treatments received, and health system resources. IMPLICATIONS FOR CANCER SURVIVORS: With over 18 million cancer survivors in the United States, many of whom experience varied symptoms and unmet needs, it is essential for health systems to have a comprehensive strategy to provide ongoing care. The US National Standards for Survivorship Care should serve as a blueprint for what survivors and their families can anticipate after a cancer diagnosis to address their needs.

Neuroendocrine Carcinoma as a Cause of Humoral Hypercalcemia of Malignancy: A Case of a Patient With Elevated Parathyroid Hormone-Related Protein.

Humoral hypercalcemia of malignancy (HHM) is a paraneoplastic syndrome caused by elevations in parathyroid hormone-related protein (PTH-rP). HHM often presents in patients with squamous cell carcinomas of the lung, head, and neck, as well as breast, ovarian, renal, and bladder carcinomas. HHM associated with neuroendocrine carcinoma (NEC) is rarely observed. Here, we report a case of NEC-associated HHM refractory to standard calcium-reducing therapies but improved with the off-label addition of cinacalcet. A 31-year-old male with metastatic NEC presented to the emergency department (ED) with symptoms of nausea, emesis, constipation, and progressive weakness. He was being treated via a clinical trial at a tertiary referral center after failing standard therapies. He had recently been admitted at an outside facility for hypercalcemia, which had been managed with denosumab (120 mg subcutaneously) over the previous four weeks. He was admitted from the ED with a serum calcium of 14.6 mg/dL, potassium of 2.9 mmol/L, and phosphate of 1.2 mg/dL; ionized calcium was elevated at 8.0 mg/dL. Despite hydration and aggressive electrolyte replacement, his calcium increased to 15.5 mg/dL. Further laboratory evaluation revealed parathyroid hormone (PTH) of 6 pg/mL (10-65 pg/mL), 25-hydroxyvitamin D of 25 ng/mL (25-80 ng/mL), 1,25-dihydroxyvitamin D of 513 pg/mL (18-64 pg/mL), and PTH-rP of 25 pmol/L (<2.5 pmol/L), consistent with HHM. Calcitonin was avoided due to a prior hypersensitivity reaction. He received prednisone 10 mg daily and pamidronate 90 mg IV, and his calcium improved to 11.5 mg/dL. He was discharged and investigational therapy was resumed. This therapy failed, and he did not qualify for additional cancer therapy due to refractory hypercalcemia. He was started on cinacalcet, and his calcium decreased enough to permit further cancer treatment. He had multiple hospitalizations with fluctuating calcium levels and ultimately died several months later after sustaining a subarachnoid hemorrhage from a fall. In conclusion, we report a rare case of HHM associated with NEC. While many cases of HHM are effectively managed with hydration, calcitonin, antiresorptive therapies, and glucocorticoids, some are refractory. Our patient was refractory and differed from most patients with HHM in at least two ways. As mentioned previously, NEC causing HHM is quite uncommon (~2% of cases); it is unclear, but this malignancy might predispose to refractory hypercalcemia. Our patient's elevated vitamin D may also have made his HHM more resistant to treatment. Ultimately, while not first line, cinacalcet was an effective treatment in our patient. This provides additional evidence that cinacalcet may be considered for refractory hypercalcemia secondary to malignancy.

Familial Essential Thrombocythemia With Novel MPL L502G and G208K Mutations.

Familial essential thrombocythemia is characterized by the inheritance of germline mutations to progeny, thereby increasing the risk for the development of essential thrombocythemia. Here, we present two cases of young women who developed thromboembolic phenomena, one of whom with an ischemic event despite adequate anticoagulation. Through extended mutational testing, both were characterized as having novel mutations in the myeloproliferative leukemia virus (MPL) gene, and both individuals have fathers being treated for essential thrombocythemia. This case provides insight that in familial essential thrombocythemia, there remain uncharacterized mutations in this inherited conditional landscape.

Near Complete Pathologic Response to PD-1 Inhibitor and Radiotherapy in a Patient with Locally Advanced Pancreatic Ductal Adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) remains deadly despite advances in systemic therapies and surgical techniques. While there is increasing utilization of immune therapies across diverse cancer types, PDAC remains generally resistant to these treatments. We report a case of locally advanced PDAC treated with preoperative radiation and anti-PD-1 immunotherapy guided by preoperative PD-L1 tumor analysis. After 4 months of preoperative therapy, the patient was submitted to resection, demonstrating a near-complete pathologic response on final tumor analysis. We will discuss the relevant literature and current state of immunotherapeutics for PDAC.

Lenalidomide-Associated Hemophagocytic Lymphohistiocytosis With Plasma Cell Phagocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a severe systemic inflammatory syndrome that is often fatal. In the adult population, it is believed to develop secondary to immune dysregulation due to rheumatologic, infectious, malignant, and recently, immunomodulatory drugs. It's co-occurrence with phagocytosis by non-macrophage cells has not been previously well defined. We present a case of lenalidomide-associated HLH with concurrent plasma cell hemophagocytosis in a patient with controlled multiple myeloma (MM).

Essential Thrombocythemia Complicated by Occlusive Thrombosis of the Abdominal Aorta.

INTRODUCTION: Essential thrombocythemia (ET) is a myeloproliferative neoplasm of excessive platelet production complicated by thrombohemorrhagic events. Thrombosis typically occurs in small to medium vessels; thrombosis of large vessels is rare. CASE PRESENTATION: A 75-year-old woman with ET complicated by bilateral retinal vein occlusion was evaluated for fatigue, early satiety, and unintentional weight loss. Her hypertension was well controlled, and her chronic lower extremity claudication from peripheral artery disease was stable. She reported adherence to aspirin 81 mg and hydroxyurea 1000 mg daily, and her platelets (375 × 109/L) were at goal. Bone marrow biopsy was consistent with ET without progression to myelofibrosis or leukemia. CT abdomen demonstrated complete occlusion of the infrarenal aorta, extending into the common iliac arteries, with reconstitution of flow distally via collaterals. The addition of clopidogrel, for platelet inhibition, and cilostazol, for claudication, caused symptom improvement without further thrombosis or bleeding. DISCUSSION: There are few published reports of ET complicated by aortic thrombosis. To our knowledge, this is the first report of aortic thrombosis occurring in an ET patient with normal platelet count on antiplatelet and cytoreductive therapies. There is limited evidence to guide treatment, but medical management with triple antiplatelet therapy may be effective in selected patients.

Hemostatic characteristics of thawed, pooled cryoprecipitate stored for 35 days at refrigerated and room temperatures.

BACKGROUND: Cryoprecipitate's shelf life is limited due to concerns over decreased clotting factor activity and contamination with extended storage. Hemostatic characteristics of thawed cryoprecipitate stored up to 35 days at refrigerated and room temperatures were assessed. STUDY DESIGN AND METHODS: Pooled cryoprecipitate was thawed and aliquoted for storage at 1-6°C or 21-24°C. Samples were tested immediately after thawing and at 4 h, 24 h, 72 h, and weekly for 35 days. At each time point fibrinogen, factor VIII (FVIII), and von Willebrand factor (vWF) were assessed. Thrombin generation and rotational thromboelastometry (ROTEM) were also performed. Further, packed red cells, platelet concentrates, frozen plasma, and stored cryoprecipitate were combined (1:1:1:1) to simulate massive transfusion and analyzed by ROTEM. Day 35 samples were cultured for bacterial contamination. RESULTS: Precipitation was observed in refrigerated samples; however, these aggregates were easily resuspended upon warming in a 37°C water bath. No significant changes were observed in fibrinogen concentration or ROTEM at either temperature. FVIII and vWF declined significantly during storage. vWF, clot time, and thrombin generation were significantly better preserved with refrigeration. With simulated massive transfusion, fibrinogen function remained at or above the established range for whole blood at both storage temperatures. Bacterial contamination was not observed in cold stored or room temperature cryoprecipitate. CONCLUSION: The fibrinogen concentration and function of cryoprecipitate at extended storage durations are adequate for fibrinogen replacement in critical bleeding. These results support extension of the shelf life of cryoprecipitate when used for fibrinogen replacement.

Next-Generation Gene Sequencing Differentiates Hypoplastic Myelodysplastic Syndrome from Aplastic Anemia.

Hypoplastic Myelodysplastic Syndrome (h-MDS) comprises 15% of all MDS and has traditionally been difficult to distinguish from aplastic anemia (AA) by current testing. Accurate differentiation is important because treatment and prognosis differ. Since the publication of the 2008 World Health Organization classification of MDS, next-generation DNA sequencing has discovered novel mutations strongly associated with AA and MDS. Recent research supports the utility of identifying these mutations in the diagnosis and management of MDS; however, use of next-generation sequencing is not yet recommended in guidelines and the study is not routinely performed. We present a case where next-generation sequencing performed on a peripheral blood specimen aided the diagnosis and management of a 74-year-old man with h-MDS. This case adds to the growing body of evidence supporting the utility of next-generation DNA sequencing in the evaluation of MDS and h-MDS, particularly when diagnosis remains unclear after standard testing.

IgG4-Related Disease: Imitating A Great Imitator.

Immunoglobulin G4-related disease (IgG4-RD) is a rare, but increasingly recognized, multi-organ fibro-inflammatory condition characterized by distinct pathologic and histologic features. The clinical variability and relative novelty of IgG4-RD make accurate diagnosis of the condition quite challenging. We report a case of a 71-year-old man presenting with hypertrophy of the facial glands and generalized lymphadenopathy who was previously diagnosed with sarcoidosis. We recognized that he had atypical epidemiologic characteristic for sarcoidosis and his prior work-up documented elevated serum IgG4 to > 300 mg/dL. Immunostaining of an axillary lymph node biopsy showed an IgG4+/IgG+ plasma cell ratio of > 40% and a plasma cell concentration of > 100 IgG4+ plasma cells per high powered field, findings consistent with the diagnosis of IgG4-RD. This case report is an example of how analysis of collective clinicopathologic data led to a diagnosis of IgG4-RD. The pathologic complexities which contribute to the elusive nature of IgG4-RD are also illustrated.

Centipede envenomation: bringing the pain to Hawai'i and Pacific Islands.

Scolopendra subspinipes is the only clinically significant centipede found in Hawai'i. Envenomation typically leads to extreme localized pain, erythema, induration, and tissue necrosis and possible lymphedema or lymphangitis. Mortality is uncommon and results from secondary infection or anaphylaxis. Management is supportive and includes wound care, pain control, and treatment with topical or oral antihistamines and anti-inflammatory medications.

Amphetamine positive urine toxicology screen secondary to atomoxetine.

The aim of this paper is to report the first case of atomoxetine leading to false-positive urine drug screen. An otherwise healthy 27-year-old female with a history of attention deficit hyperactivity disorder (ADHD) treated with atomoxetine had an acute onset tonic-clonic seizure. On arrival to the hospital, a urine toxicological drug screen with immunochemical cloned enzyme donor immunoassay (CEDIA) was performed. Results were positive for amphetamines; however, the presence of these substances could not be confirmed with urine gas chromatography-mass spectrometry (GC-MS). She denied any illicit drug use, herbal medications, or supplements, and her other prescription medications have not been previously known to cause a false-positive result for amphetamines. While stimulant treatments for ADHD could certainly result in a positive result on urine screen for amphetamines, there have been no reports of false-positive results for amphetamines secondary to patients using atomoxetine. We implicate atomoxetine, and/or its metabolites, as a compound or compounds which may interfere with urine drug immunoassays leading to false-positive results for amphetamines CEDIA assays.
