We demonstrate that detection of CTCs overexpressing PD-L1 is feasible and may provide important prognostic information in HNSCC. Our results suggest that adjuvant PD1 inhibitors deserve evaluation in HNSCC patients in whom PD-L1(+) CTCs are detected at the end of curative treatment.
Ovarian lymphoma is a rare entity. Clinicians should be aware of its clinical manifestations and management since surgery alone often is not adequate treatment. Here, we present two cases of ovarian lymphoma and discuss what is known about ovarian lymphoma.
The current study proposes the incorporation of Ki-67 index in the prognostic classification of PC tumours. Due to the limited number of patients and length of follow-up, the current model needs validation by larger cohort studies. Nevertheless, our results suggest that Ki-67 index and MI have continuous effect on prognosis. Prognostic models incorporating multiple cutoffs of Ki-67 and MI might better predict outcome and inform clinical decisions.
MALT lymphomas represent a distinct disease entity with widespread extranodal origin, indolent clinical course and high chemosensitivity. Ann Arbor stage was the most reliable prognostic and predictive factor.
BackgroundImmune‐checkpoint inhibitors have been shown to improve survival in melanoma patients, but can also trigger immune‐related endocrinopathies, especially hypophysitis and thyroid dysfunction.MethodsTo assess the incidence and the spectrum of endocrinopathies in melanoma patients treated with immunotherapy a prospective observational study was conducted. Forty out of 339 patients, treated with immune‐checkpoint inhibitors, developed endocrinopathies. All patients had hormonal functional tests at screening (before the initiation of immunotherapy) and during follow‐up.ResultsThe total incidence of endocrinopathies was 11.8%, 13.4% due to anti‐PD1/PDL1, 5% due to anti‐CTLA4, and 18.5% due to sequential and/or combination treatment. Twenty‐one patients (6.2%) presented with isolated anterior hypophysitis, eleven (3.2%) with primary thyroid dysfunction and eight (2.4%) with both abnormalities. The most frequent anterior pituitary hormone deficiency was central adrenal insufficiency, followed by central hypothyroidism and hypogonadotrophic hypogonadism. None of the patients with corticotroph axis failure recovered during follow‐up. Endocrinopathies occurred after a median of 22 weeks (range: 4‐156) from treatment initiation. Of note, sequential and/or combination therapy with anti‐CTLA4 and anti‐PD1/anti‐PDL1 led to an almost threefold incidence of hypophysitis compared to either monotherapy. Only one of 120 patients receiving anti‐CTLA4 monotherapy developed primary hypothyroidism.ConclusionsOur cohort demonstrated an increased incidence of hypophysitis with anti‐PD1/anti‐PDL1 in contrast to the rarity of primary thyroid dysfunction with anti‐CTLA4 treatment. These results could be attributed to genetic/ethnic differences. Sequential treatment is, for the first time to our knowledge, reported to increase the risk of developing hypophysitis to a level as high as that of combination therapy.
The widespread use of immune checkpoint inhibitors has shed light to several unusual immune-related adverse effects of the drugs. Severe cutaneous adverse reactions are generally rare with anti-PD1 agents. We present in this paper the case of a 48-year-old patient with melanoma who developed bullous pemphigoid-like skin lesions along with fever, arthralgia and overt eosinophilia following adjuvant treatment with nivolumab. The condition was successfully treated with corticosteroids and a rechallenge with another anti-PD1 agent did not lead to recurrence of the skin lesions. We also reviewed the literature on the epidemiologic, clinical, and histopathologic characteristics of bullous pemphigoid as well as on the treatment and prognosis of this dermatologic condition in patients with melanoma or other malignancies under treatment with immune checkpoint inhibitors.
Background: Temozolomide and capecitabine (CAPTEM) chemotherapy is known to be active in patients with pancreatic neuroendocrine tumours. Objective: This retrospective analysis set out to describe the efficacy and toxicity of CAPTEM in patients with advanced pulmonary carcinoids (PCs). Methods: Patients were included with advanced PC who had been treated with a maximum of 6 cycles of oral temozolomide 200 mg/m2 on days 10–14 and capecitabine 750 mg/m2 b.i.d. on days 1–14, repeated every 28 days, followed by monthly intramuscular injection of octreotide 30 mg long-acting release as maintenance treatment. Results: Of the 33 patients, all with well-differentiated PC, 61% had atypical carcinoid, 36% had Ki-67 index >10% and 42% had ≥3 organs involved by metastasis. CAPTEM was administered as first-line treatment in 42% of patients, and 17% had received prior somatostatin analogue treatment. Six patients (18%) achieved a partial response, 19 (58%) had stable disease and 8 (24%) developed progressive disease. After a median time of follow-up of 34.8 months, median progression-free survival (PFS) was 9.0 months and median overall survival 30.4 months. Median duration of disease response was 21.7 months and median duration of disease control 9.7 months. Patients with multi-organ metastasis had shorter PFS, but only when treated as second or third line with CAPTEM (p = 0.023). Conclusions: CAPTEM induced a modest response and PFS rate, comparable to other studies with temozolomide in patients with advanced PC. The efficacy of CAPTEM should be compared to that of monotherapy with temozolomide in a prospective clinical trial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
