Abstract
RATIONALE Sintilimab is a novel programmed cell death receptor-1 (PD-1) inhibitor approved in the treatment of classical Hodgkin's lymphoma and undergoing clinical trials for various malignancies. As a PD-1 inhibitor, sintilimab is known to cause autoimmune adverse events similar to other PD-1 inhibitors. Diabetic ketoacidosis (DKA) is a rare but severe adverse event of this therapy. PATIENT CONCERNS We report a case of a 59-year-old man who developed DKA after 5 doses of sintilimab for small cell lung cancer. His fasting glycemia level was 14.07 mmol/L, urine ketone bodies were 4+, arterial blood pH was 7.271, bicarbonate was 12.3 mmol/L, and glycated hemoglobin (HbA1c) was 7.4%. Extended investigations revealed that fasting C-peptide was undetectable (<0.003 nmol/L). DIAGNOSIS These laboratory investigations supported the diagnosis of fulminant type 1 diabetes mellitus, but no β-cell related antibodies were positive. INTERVENTIONS After remission of DKA, he was treated with insulin therapy to acquire a normalization of glycemia and the disappearance of symptoms. OUTCOMES Sintilimab was withheld after 6 cycles and was converted to durvalumab to sustain the therapeutic effect. LESSONS This case and associated literature review illustrate the importance of educating and monitoring patients who start PD-1 inhibitor therapy regarding this potentially life-threatening complication.

Puliafito, I, Russo, A, Sciacca, D, Puglisi, C, Giuffrida, D
Journal of medical case reports. 2020;(1):7
Abstract
BACKGROUND Pazopanib is a multitarget tyrosine kinase inhibitor used in the treatment of renal cancer and soft tissue sarcoma. Its use is commonly associated with a number of side effects, such as hemorrhagic diathesis, neutropenia, leukopenia, thrombocytopenia, nausea, vomiting, abdominal pain, increased serum aspartate aminotransferase, increased serum alanine aminotransferase, decreased serum glucose, increased serum bilirubin, decreased serum phosphate and magnesium, fatigue, hypertension, diarrhea, anorexia, proteinuria, and hypothyroidism. Abscesses of metastases caused by pazopanib administration are rarely reported in the literature. CASE PRESENTATION We report a case of abscesses of lung metastases related to pazopanib in a patient with metastatic renal cancer. The patient was a 53-year-old Caucasian man who developed abscesses of lung metastases during the first 3 months of treatment with pazopanib. The abscesses resolved after 1 month by stopping pazopanib and administering adequate antibiotic therapy. CONCLUSIONS We conclude that abscesses of metastases could be a rare side effect occurring during treatment with pazopanib in patients with renal cancer.

Abstract
Immune checkpoint inhibitors (ICIs) have improved the overall survival of many patients with advanced cancers. However, unlike cytotoxic and targeted drugs, ICIs may cause various immune-related adverse events (irAEs). Among these irAEs, autoimmune meningitis is very rare. Here, we report a case of early-onset, atezolizumab-induced meningitis after administration of one dose of atezolizumab. A 56-year-old man with lung adenocarcinoma had received seventh-line treatment with atezolizumab when he experienced dysarthria. Blood examinations, including the measurement of electrolytes, glucose, and organ functions, were unremarkable, but enhanced head magnetic resonance imaging T1-weighted images showed meningeal enhancement. Although cerebral spinal fluid (CSF) examinations revealed elevated lymphocyte and protein levels, no cancer cells were detected in the CSF. CSF cultures and serological tests, including polymerase chain reaction for herpes simplex virus, were negative. The patient was therefore diagnosed with atezolizumab-triggered autoimmune meningitis. With steroid treatment, the patient's clinical and neurological state improved immediately and he recovered to baseline conditions. Prompt diagnosis and therapeutic intervention are essential for the effective treatment of autoimmune meningitis.

Acquired haemophilia A in a patient with breast cancer and lung carcinoma: a case report and literature review.
Biesheuvel, V, Hiddema, SM, Levenga, H, Eikenboom, J, van der Deure, WM
The Netherlands journal of medicine. 2019;(4):153-155
Abstract
Acquired haemophilia A is a rare disorder caused by spontaneous formation of auto-antibodies (inhibitors) against coagulation factor VIII. This can lead tolife-threatening haemorrhages. Six to twenty-two percent of patients with acquired haemophilia have an underlying malignancy. We describe a 69-year-old woman with metastatic breast cancer and non-small cell lung carcinoma who presented at the emergency room with spontaneous bruising, and who was using a vitamin K antagonist. She had a prolonged activated partial thromboplastin time (aPTT) due to a coagulation factor VIII deficiency caused by factor VIII antibodies. She was treated with prednisone and cyclophosphamide.

Abstract
RATIONALE Chylothorax is usually diagnosed within a few days after lobectomy. Late-onset chylothorax following trauma or thoracic surgery is rare but potentially lethal, lacking reliable preventive methods. PATIENT CONCERNS A 54-year-old male patient complained of dyspnea during adjuvant chemotherapy on the 35th postoperative day after right middle lobectomy and systemic lymph node dissection (SLND) for lung cancer. His computed tomography indicated massive pleural effusion filling in the right chest cavity. DIAGNOSES The patient was primarily diagnosed as late-onset chylothorax, without definite evidence to exclude spontaneous chylous leakage. INTERVENTIONS Uniportal video-assisted thoracoscopic thoracic duct ligation (TDL) was performed for him, as conservative treatment using octreotide with fat-free diet turned out to be ineffective. OUTCOMES His pleural effusion was gradually diminished after reoperation, and the patient was discharged 9 days after TDL. LESSONS Postoperative late-onset or spontaneous chylothorax should be kept in mind after pulmonary resection and SLND, and the exclusion of chylous leakage could be considered as a precondition of chest tube removal.

Abstract
RATIONALE Drug-induced pancreatitis (DIP) is a rare type of pancreatitis that is not usually observed in the clinical practice. It is generally difficult to distinguish from acute pancreatitis (AP) induced by other causes. PATIENT CONCERNS Here, we report a 62-year-old Chinese female patient with "small cell lung cancer" as the initial presentation. Because the patient could not bear the surgical treatment, the chemotherapy composed of lobaplatin and etoposide was performed. Three days later, the patient displayed sudden abdominal pain, distension, nausea, and vomiting without obvious inducements. Laboratory tests showed that the levels of serum and urine amylase were enhanced; abdominal computed tomography (CT) result showed the enlargement of the pancreas, peripancreatic effusion, and a rough edge, which suggested the diagnosis of AP. The patient had no history of biliary tract disease, alcoholism, binge overeating, hyperlipidemia, and hereditary pancreatitis. DIAGNOSES The patient was diagnosed with DIP. INTERVENTIONS The chemotherapy was stopped at once and we performed fluid resuscitation, pain alleviation, prophylactic antibiotics, and nutritional support, etc on the patient. Later, the patient's clinical symptoms were obviously relieved, and she recovered successfully. OUTCOMES The chemotherapy was continued, but later, the patient showed abdominal pain, distension, nausea, and vomiting again. The levels of serum amylase and urine amylase were enhanced again. Further imaging examination strongly indicated the recurrence of AP. LESSONS We should raise awareness of the clinicians regarding DIP, thereby enabling its timely diagnosis and accurate treatment, as well as promoting the rational and safe use of drugs.

Abstract
RATIONALE Immune checkpoint inhibitors have led to the development of new approaches for cancer treatment with positive outcomes. However, checkpoint blockade is associated with a unique spectrum of immune-related adverse events (irAEs), which may cause irreversible neurological deficits and even death. PATIENT CONCERNS We presented a case of a 57-year-old man with non-small-cell lung cancer.who developed ptosis, dyspnea, and muscle weakness as initial symptoms with progression after the treatment with ipilimumab and nivolumab. DIAGNOSES Myasthenia gravis was confirmed by serum acetylcholine receptor antibody and single fiber electromyography. Myositis was identified by high level of serum creatine phosphokinase and electromyography. Polyneuropathy was identified by nerve conduction study. INTERVENTIONS The patient underwent treatment with steroid and pyridostigmine. Respiratory rehabilitation was also performed. OUTCOMES Dyspnea and muscle weakness improved gradually. Ipilimumab and nivolumab were permanently discontinued. LESSONS This case has increased the clinical awareness by indicating that the checkpoint inhibitors-related neurological irAEs could be complicated and simultaneously involve multiple neurological systems. Early recognition and complete evaluation are critical in clinical practice.

Abstract
PURPOSE OF REVIEW Cancer cachexia is common and reduces function, treatment tolerability and quality of life. Given its multifaceted pathophysiology a multimodal approach to cachexia management is advocated for, but can be difficult to realise in practice. We use a case-based approach to highlight practical approaches to the multimodal management of cachexia for patients across the cancer trajectory. RECENT FINDINGS Four cases with lung cancer spanning surgical resection, radical chemoradiotherapy, palliative chemotherapy and no anticancer treatment are presented. We propose multimodal care approaches that incorporate nutritional support, exercise, and anti-inflammatory agents, on a background of personalized oncology care and family-centred education. Collectively, the cases reveal that multimodal care is part of everyone's remit, often focuses on supported self-management, and demands buy-in from the patient and their family. Once operationalized, multimodal care approaches can be tested pragmatically, including alongside emerging pharmacological cachexia treatments. SUMMARY We demonstrate that multimodal care for cancer cachexia can be achieved using simple treatments and without a dedicated team of specialists. The sharing of advice between health professionals can help build collective confidence and expertise, moving towards a position in which every team member feels they can contribute towards multimodal care.

Pituitary metastasis of lung neuroendocrine carcinoma: case report and literature review.
Siqueira, PF, Mathez, AL, Pedretti, DB, Abucham, J
Archives of endocrinology and metabolism. 2015;(6):548-53
Abstract
Metastasis to the pituitary gland is an unusual situation in clinical practice, but the frequency thereof is increasing due to the increased survival of cancer patients, and greater availability of imaging. In most cases, they are found between the sixth and seventh decades of life, as determined in image examination of patients with known malignant neoplasm, but, generally, asymptomatic with respect to pituitary involvement. The most common primary sites are breast in women and lung in men. We present the case of a 64-year-old patient with clinical visual changes, polyuria, polydipsia, and decreased level of consciousness whose tests showed pan-hypopituitarism, hypernatremia and low urine specific gravity, and extensive mass in sellar region. Diabetes insipidus was confirmed and treated, corticotrophic and thyroid deficits were corrected and then the patient underwent resection by transsphenoidal surgery. The histopathological and immunohistochemistry analysis revealed pituitary metastasis of lung neuroendocrine tumor. Subsequently, a chest CT scan showed pulmonary mass consistent with primary neoplasm. Despite the water and electrolyte correction and intravenous glucocorticoid replacement, the patient continued to show decreased level of consciousness due to compression of the brain stem by the pituitary mass, evolving to death. The purpose is to call attention to the differential diagnosis of invasive lesions of the sellar region, mainly in individuals over 50 years and/or when associated with diabetes insipidus, as it may be a case of metastasis, although there is no known primary neoplasm.

Abstract
UNLABELLED A 75-year-old man, undergoing treatment for metastatic prostate cancer with a novel cancer cell vaccine, presented with a 4 week history of poor balance, gait disturbance and cognitive decline. Blood tests including HIV and onconeuronal and voltage gated potassium channel antibodies were normal. Computed tomography and two magnetic resonance images of the brain showed possible non-specific meningeal or vascular enhancement. Two cerebrospinal fluid analyses, including cytology, were negative, other than six lymphocytes in the former. Despite intravenous aciclovir and dexamethasone the patient deteriorated over 16 days, with worsening confusion and involuntary movements, and died. Postmortem examination showed that the leptomeninges overlying the brain and spinal cord were diffusely infiltrated by a melanocytosis with a focal area of melanomatosis. Moreover, there were two sites of metastases of a highly malignant clone present in the pulmonary parenchyma. TRIAL REGISTRATION NUMBER NCT00133224.
