Neuroendocrine neoplasms of the breast: a review of literature.

Primary neuroendocrine neoplasms (NENs) of the breast are characterized by neuroendocrine architectural and cytological features, which must be supported by immunohistochemical positivity for neuroendocrine markers (such as Chromogranin and Synaptophysin). According to the literature, making a diagnosis of primary neuroendocrine breast cancer always needs to rule out a possible primary neuroendocrine neoplasm from another site. Currently, the latest 2022 version of the WHO of endocrine and neuroendocrine neoplasms has classified breast NENs as well-differentiated neuroendocrine tumours (NETs) and aggressive neuroendocrine carcinomas (NECs), differentiating them from invasive breast cancers of no special type (IBCs-NST). with neuroendocrine features. The current review article describes six cases from our series and a comprehensive review of the literature in the field of NENs of the breast.

Clinical and immunophenotype correlating with response to immunotherapy in paediatric patients with primary liver carcinoma. A case series.

BACKGROUND: Paediatric hepatocellular carcinomas (HCC) traditionally arise in the context of a normal structural and functional liver and carry a dismal prognosis. While chemotherapy is the frontline standard, there is emerging interest in the study of immunotherapies for paediatric patients with relapsed/refractory disease. There is limited data to support whether immunotherapies will be of utility in this patient population. METHODS: Six paediatric patients (median age:16 years, range: 12-17 at the time of treatment) with advanced hepatocellular neosplams, either conventional hepatocellular or fibrolamellar carcinoma, were treated with immunotherapy. Patients were consented to institutional genomic profiling and biobanking protocols. Baseline samples and serial tissue samples, when available, were evaluated for somatic mutation rate, actionable gene mutations, and pan-immune bulk RNA expression profiling. Results were correlated with clinical course. FINDINGS: Three patients responded to checkpoint inhibition: one achieved a complete, durable response and the other two, prolonged stable disease. Three additional patients progressed. Diagnostic tissue from the complete responder demonstrated a higher relative mutational burden and robust immune infiltrate. Pre-treatment samples from the three responders demonstrated decreased expression of genes associated with T-cell dysfunction. INTERPRETATION: A subset of patients with primary paediatric hepatocellular tumours will respond to immunotherapy. Immunotherapies are currently under prospective study for relapsed/refractory liver tumours in paediatric patients. Results from this report support the prospective collection of serial serum and tissue samples which may further identify genomic and immunophenotypic patterns predictive of response. FUNDING: This work was supported by Philanthropic funds (Pan Mass Challenge, Team Angus and Team Perspective).

Metastases to the parotid glands: An institutional experience.

BACKGROUND: Metastatic lesions to the salivary gland are rare and mostly affect the parotids. Metastases represent 8% of all malignant lesions of the parotid gland. Around 80% originate from squamous cell carcinomas (SCC) of the head and neck region. Fine needle aspiration (FNA) plays a crucial role in distinguishing primary salivary gland lesions from metastases. Herein we describe our series of metastases to the parotid glands. MATERIALS AND METHODS: We analysed 630 parotid gland FNAs over a decade including conventional and liquid-based cytology specimens. Ancillary techniques such as immunocytochemistry (ICC) were conducted on cell blocks. RESULTS: Eighty (12.4%) cases were malignant lesions, of which 53 (63.75%) were metastases including 24% melanoma, 22.6% SCC, 19% renal carcinomas, 7.5% breast carcinomas, 11.3% lung, 9% intestinal and 1.8% testicular, malignant solitary fibrous tumour and Merkel cell carcinoma. The 53 cases, classified according to the Milan system for salivary cytopathology, belonged to 5 Suspicious for malignancy (SFM) and 48 malignant (M) categories. Forty had a known history of primary malignancy (75.4%), while 13 were suspicious to be a metastatic localisation (24.5%), distributed as 5SFM (2SCC and 3Melanoma) and 8 M. A combination of clinical history, cytomorphology and ICC identified 100% of them. CONCLUSIONS: Fine needle aspiration plays a central role in the diagnostic workup of patients with metastatic lesions to their parotid glands, thereby defining the correct management. Diagnostic accuracy may be enhanced by applying ICC. Although melanoma and SCC are the most common histological types, several other malignancies may also metastasize to the parotid glands and should be kept into consideration.

Some uncommon cystic lesions in the anterior head and neck region: Pitfalls to be avoided on cytology.

Cystic lesions of the anterior head and neck region are a challenging and frequent finding on cytological smears. The scant amount of cellular material in cystic slides poses the greatest difficulty to interpretation, so that frequently they are diagnosed as inadequate or with minimal cellular component. Despite the majority of cystic lesions being benign, a minor portion consist of malignant cystic entities. In these latter cases, the evidence of very scant malignant cells can be misdiagnosed and/or underestimated, leading to a false negative diagnosis. Many papers have already described and detailed the range of possible benign and malignant cystic lesions in head and neck. In the current review we have focused on the less common entities that often lead to serious misinterpretation.

Updates from Our Institutional Experience with Thyroid Nodules Diagnosed as Metastases.

BACKGROUND: Thyroid metastases (TMs) are a rare entity, ranging between 0 and 24% in the autopsy series. In the assessment of the best management, the discrimination between a primary and a metastatic thyroid lesion is crucial. In this regard, fine needle aspiration cytology (FNAC) is likely to play a crucial role especially when ancillary techniques (i.e., immunocytochemistry (ICC) and molecular testing) are carried out. METHODS: We searched for all the TMs diagnosed using FNAC and analyzed between 2014 and 2023. The cases were processed with liquid-based (LBC) and ICC and molecular testing performed on LBC-stored material. RESULTS: We reported 2.2% (19 cases) of TMs out of 1022 malignancies. TMs included: 1 larynx carcinoma (LX-Ca), 1 melanoma, 2 breast carcinomas (B-Ca), 3 lung carcinomas (LG-Ca), 4 gastro-intestinal carcinomas (GI-Ca), and 8 clear cell renal carcinomas (CCRC). All patients had a previous cancer history, between 300 and 2 months from the primary cancers. The morphological features were supported by ICC, which were contributive in 100% of cases. All TMs cases were characterized by multiple thyroid nodules except the melanoma case. Four cases underwent total thyroidectomy (1 B, 1 LX, 1 melanoma, and 1 CCRC) whilst 15 TMs were treated with radio-chemotherapy. CONCLUSIONS: FNAC empowered the diagnostic workup of patients with TMs avoiding useless surgery. The low sensitivity of cytology might be reinforced by the application of ancillary techniques. We found a predominant rate of kidney metastatic carcinomas, followed by lung and breast. TMs are frequently multifocal and in a context of a systemic disease so a tailored therapy seems to be the best treatment.

Diagnostic role of FNA cytology in the evaluation of cervical lymph nodes in thyroid cancers: Combined evaluation of thyroglobulin in eluate from FNA cytology.

BACKGROUND: The presurgical evaluation of cervical lymph nodes (CLNs) in the management of thyroid malignant lesions is crucial for the extent of surgery or detection of metastases. In these last decades, fine-needle aspiration cytology (FNAC) has been shown to have a central role in the detection of nodal thyroid metastases. It is adopted for the possibility of confirming suspected metastases either in the presurgical phase or in the follow-up of patients after thyroidectomy. However, FNAC from CLNs can be challenging, especially in cystic lesions. In this regard, the combination of FNAC with thyroglobulin measurement in the eluate from FNAC (Tg-FNAC) seems to increase the sensitivity of FNAC in the detection of CLN metastases. The role of FNAC and Tg-FNAC was investigated in this series. METHODS: One hundred fifty-three prospective cytological samples of CLNs were studied along with surgical follow-up in the period between 2020 and 2022. Immunocytochemistry (ICC) was performed on liquid-based cytology-stored material. RESULTS: One hundred fifty-nine enlarged CLNs included 19 central lymph nodes and 140 CLNs. Forty-two thyroidal CLN metastases and 117 reactive lymph nodes were found. Thirty-one CLN dissections were performed in patients with a previous diagnosis of thyroid carcinoma (mostly papillary thyroid carcinoma [PTC]), whereas 128 CLNs with a concomitant suspicious and/or malignant thyroid nodule were found. There was one false-positive case among all the malignant histologically confirmed cases, and two of 117 reactive CLNs (1.7%) had a diagnosis of metastatic PTC. Markedly high Tg-FNAC was found in all metastatic CLNs, including 11 cystic metastatic CLNs detected by Tg-FNAC with a negative FNAC. ICC (including Tg, CK-19, and LCA) recognized nine cases with low Tg-FNAC and scant suspicious thyrocytes. Tg-FNAC plus FNAC diagnosed 94.2% of malignancies. CONCLUSIONS: FNAC represents a valid method for the evaluation of CLNs, especially combined with ICC. Tg-FNAC is an additional method with a useful role in FNAC.

Cystic lesions in the salivary gland. Pitfalls to be avoided on cytology.

Cystic lesions of the salivary glands are very uncommon entities. However, on occasion, some neoplasms of the salivary glands show a cystic component, which may be predominant or only partially cystic. Basal cell adenoma, canalicular adenoma, oncocytoma, sebaceous adenoma, intraductal papilloma, epithelial-myoepithelial carcinoma, intraductal carcinoma, and secretory carcinoma are such cystic entities. Cystic degeneration and necrosis, which can develop within solid tumours, represent another possibility. The ability to recognise this type of lesion is a challenge in diagnostic cytology because hypocellular fluid is frequently recovered. Furthermore, evaluating all of the differential diagnoses for cystic lesions of the salivary glands is helpful in obtaining the correct diagnosis. Herein, we evaluate the various types of cystic lesions within the salivary glands.

A single-institution pediatric and young adult interventional oncology collaborative: Novel therapeutic options for relapsed/refractory solid tumors.

BACKGROUND: Pediatric interventional oncology (PIO) is a growing field intended to provide additional or alternative treatment options for pediatric patients with benign or malignant tumors. Large series of patients treated uniformly and subjected to rigorous endpoints for efficacy are not available. METHODS: We designed a collaborative initiative to capture data from pediatric patients with benign and malignant tumors who underwent a therapeutic interventional radiology procedure. Modified Response Evaluation Criteria in Solid Tumors (mRECIST) was utilized as a measure of radiologic response and data were collected regarding improvement in pain and functional endpoints. Cumulative incidence of progressive disease was calculated using both the treated site and the patient as the analytic unit. FINDINGS: Forty patients, 16 with malignant tumors and 24 with benign tumors, underwent a total of 88 procedures. Cryo- and radiofrequency ablation were the most frequently utilized techniques for both cohorts of patients. A complete or partial response, or prolonged disease stability, were achieved in approximately 40% of patients with malignant tumors and 60% of patients with benign tumors. No patients had progressive disease as their best response. Resolution of pain and improved mobility with return-to-baseline activity were demonstrated across patients from both cohorts. Only minor complications were experienced. INTERPRETATION: Interventional radiology-guided interventions can serve as an alternative or complementary approach to the treatment of benign and malignant tumors in pediatric patients. Prospective, multi-institutional trials are required to adequately study utility, treatment endpoints, and durability of response.

Adaptation of the Day100 Talk communication intervention for Spanish-speaking families of children with cancer.

The Day100 Talk (Day100) bridges communication gaps between parents and clinicians early in pediatric cancer care through an interprofessional family conference facilitated by structured tools. We aimed to understand communication challenges and facilitators and to adapt Day100 for Spanish-speaking parents. We interviewed Spanish-speaking parents with limited English proficiency, Spanish-English medical interpreters, and clinicians to gather communication experiences and adapt Day100. Results showed that communication difficulties were precipitated by linguistic and cultural differences, nonvisual technologies, and limited spontaneous communication. Interpreters enhanced communication as linguistic and cultural brokers. Nonverbal cues also facilitated communication. Participants offered recommendations to adapt Day100 for future study.

Normalization of Symptoms in Advanced Child Cancer: The PediQUEST-Response Case Study.

CONTEXT: Children, adolescents and young adults with cancer continue to experience significant symptom suffering throughout their illness. OBJECTIVES: To identify barriers to effective symptom management in pediatric advanced cancer. METHODS: Using a qualitative multiple case study we refined the Pediatric Quality of Life and Evaluation of Symptoms Technology Response to the Pediatric Oncology Symptom Experience (PediQUEST Response), a pediatric palliative care (PPC) intervention. Twenty-three children aged ≥2 years old with advanced cancer, their parents and primary and PPC clinicians were enrolled. Children and parents reported symptoms weekly over 4-months using the Memorial Symptom Assessment Scale (MSAS) administered by an electronic system (PediQUEST). When symptom distress episodes (SDEs) were reported (MSAS symptom score ≥33) we studied symptom management processes using interviews of family members/clinicians, and chart abstractions. Data were coded and analyzed using grounded theory and NVivo software. RESULTS: Children reported 308 SDEs within 193 surveys and parents 529 SDEs in 165 surveys administered. We conducted 85 and 88 interviews with families and clinicians respectively. While we confirmed the presence of known barriers, we identified a prominent theme, that symptoms were "normalized." Patients, parents, and all clinicians, including PPC specialists, got accustomed to high symptom burden and lacked expectations that distress could be alleviated. We defined "normalization of symptoms," as the process by which symptom related suffering is appraised as unavoidable. CONCLUSION: Normalization of symptoms is a pervasive barrier enacted by all involved in caring for children with advanced cancer. Strategies to overcome normalization are critical to ease child distress.

Feasibility and acceptability of the "Day 100 Talk": An interdisciplinary communication intervention during the first six months of childhood cancer treatment.

BACKGROUND: Communication gaps arise early in the childhood cancer trajectory and may persist. The authors conducted a pilot study of the feasibility and acceptability of a communication intervention, the Day 100 Talk (D100). D100 involves an interprofessional family conference during initial months of treatment between oncologists, psychosocial clinicians, and parents, facilitated by a 3-part conversation tool. METHODS: The authors enrolled English-speaking parents of children with nonrelapsed, nonprogressive cancer who were receiving continuity care from enrolled pediatric oncologists and psychosocial clinicians at a single site. The a priori feasibility threshold was 60% parent completion of the D100 intervention. Surveys from parents and professionals and debrief interviews with professionals assessed D100 acceptability. RESULTS: Thirty-seven parents (77%) and 38 oncology professionals (67%) enrolled. Twenty of 33 evaluable parents (61%) participated in a D100 family conference. Most commonly, parents did not complete the D100 intervention because of scheduling difficulties related to clinical team constraints. All 17 parents who completed a post-D100 survey agreed or strongly agreed that D100 participation was helpful. In debrief interviews, professionals identified D100 benefits, namely, stepping back to the big picture and getting on the same page, and barriers related to logistical challenges and professionals' anticipatory dread. CONCLUSIONS: The D100 intervention pilot demonstrates high acceptability among parents of children with cancer. Despite meeting the prespecified feasibility threshold, findings highlight important barriers to D100 dissemination, namely, perceived burdens on professionals. Potential strategies to reduce burden may include using virtual visit platforms, incorporating D100 elements across multiple visits, or prioritizing intervention delivery to parents with the greatest need for enhanced communication.

Neuroendocrine Carcinoma of the Uterine Cervix: A Clinicopathologic and Immunohistochemical Study with Focus on Novel Markers (Sst2-Sst5).

BACKGROUND: Gynecological neuroendocrine neoplasms (NENs) are extremely rare, accounting for 1.2-2.4% of the NENs. The aim of this study was to test cervical NENs for novel markers of potential utility for differential diagnosis and target therapy. METHODS: All cases of our center (n = 16) were retrieved and tested by immunohistochemistry (IHC) for 12 markers including markers of neuroendocrine differentiation (chromogranin A, synaptophysin, CD56), transcription factors (CDX2 and TTF1), proteins p40, p63, p16INK4a, and p53, somatostatin receptors subtypes (SST2-SST5) and the proliferation marker Ki67 (MIB1). RESULTS: All cases were poorly differentiated neuroendocrine carcinomas (NECs), 10 small cell types (small cell-neuroendocrine carcinomas, SCNECs) and 6 large cell types (large cell-neuroendocrine carcinomas, LCNECs); in 3 cases a predominant associated adenocarcinoma component was observed. Neuroendocrine cancer cells expressed at least 2 of the 3 tested neuroendocrine markers; p16 was intensely expressed in 14 (87.5%) cases; SST5 in 11 (56.25%, score 2-3, in 9 cases); SST2 in 8 (50%, score 2-3 in 8), CDX2 in 8 (50%), TTF1 in 5 (31.25%), and p53 in 1 case (0.06%). P63 and p40 expressions were negative, with the exception of one case that showed moderate expression for p63. CONCLUSIONS: P40 is a more useful marker for the differential diagnosis compared to squamous cell carcinoma. Neither CDX2 nor TTF1 expression may help the differential diagnosis versus potential cervical metastasis. P16 expression may suggest a cervical origin of NEC; however, it must be always integrated by clinical and instrumental data. The expression of SST2 and SST5 could support a role for SSAs (Somatostatin Analogues) in the diagnosis and therapy of patients with cervical NECs.

Parent Perceptions of Team-Delivered Care for Children With Advanced Cancer: A Report From the PediQUEST Study.

CONTEXT: Childhood cancer care is delivered by interprofessional health care teams; however, little is known about how parents perceive overall team-delivered care (TDC). OBJECTIVES: We sought to describe parent perceptions of TDC and associated factors, including care rendered by individual clinicians, teamwork, information consistency, and patient and parent characteristics. METHODS: Cross-sectional surveys were distributed to parents of 104 children with recurrent/refractory cancer enrolled in a multisite symptom management trial. The primary outcome, TDC, was parent report of care quality delivered by the child's care team during the preceding three months. Likert-scaled items (excellent/very good/good/fair/poor) queried care quality delivered by individual clinicians, perceived teamwork, and other factors. Factors associated with parent perceptions of excellent TDC were identified using Fisher's exact test. RESULTS: Eighty-six parents (83%) responded. During the preceding three months, 63% (n = 54) of parents reported excellent TDC. However, only 47% (n = 40) described their care team's teamwork as excellent. Approximately one-quarter (24%) described care rendered by their child's oncologist as less-than-excellent. Among parents who reported psychosocial clinician involvement (71%; n = 60), only 43% described this care as excellent. Individually, excellent care from each clinician type (oncologist, psychosocial clinician, and primary nurse) was associated with excellent TDC (all P ≤ 0.001; no correction for multiple comparisons). CONCLUSION: Among parents of children with advanced cancer, more than one-third report less-than-excellent TDC. In addition, less than half report excellent teamwork, and ratings of care rendered by individual clinicians are highly variable. Findings suggest that interventions are needed to enhance interprofessional teamwork in the care of children with advanced cancer.

Cancer Treatment-Related Infertility: A Critical Review of the Evidence.

Cancer treatments may compromise the fertility of children, adolescents, and young adults, and treatment-related infertility represents an important survivorship issue that should be addressed at diagnosis and in follow-up to ensure optimal decision-making, including consideration of pursuing fertility preservation. Risk of infertility varies substantially with patient and treatment factors. The ability to accurately assess fertility risk for many patients is hampered by limitations of the current literature, including heterogeneity in patient populations, treatments, and outcome measures. In this article, we review and synthesize the available data to estimate fertility risks from modern cancer treatments for both children and adult cancer survivors to enable clinicians to counsel patients about future fertility.

"What if?": Addressing uncertainty with families.

Children with cancer and their families deal with uncertainty throughout their treatment course. Clinicians must help patients and families manage uncertainty by engaging them in discussions about their worries and fears. Too often, clinicians avoid or defer discussions about anticipated or worried-about future events-the "what ifs." Failing to engage in these conversations may lead to increased distress. We have developed a framework for having "what if" conversations with patients and families that enables providers to explore families' informational and emotional needs. This framework may enable providers to improve families' prognostic understanding, explore concerns, and examine preferences and goals of care.

Intimate Partner Relationships, Work-Life Factors, and Their Associations With Burnout Among Partnered Pediatric Residents.

BACKGROUND: Burnout is prevalent among pediatric residents, and reducing burnout is a priority for pediatric residency programs. Understanding residents' personal circumstances, including relationship satisfaction and perceived work-life conflict, may identify novel determinants of burnout. OBJECTIVES: To describe intimate partner relationships among pediatric residents and examine associations among relationship satisfaction, work-life factors, and burnout. METHODS: We identified 203 partnered residents (married or in a self-identified committed, ongoing relationship) from a cross-sectional survey of 258 residents in 11 New England pediatric programs (response rate 54% of 486 surveys distributed), conducted from April through June of 2013. We analyzed associations among relationship satisfaction, work-life factors, and burnout using multivariable regression. Burnout was measured with the brief Maslach Burnout Inventory, and relationship satisfaction with the validated Relationship Assessment Scale. RESULTS: Burnout was reported by 40.9% of partnered respondents. The vast majority of partnered residents (n = 167; 85.2%) reported high relationship satisfaction. Lower relationship satisfaction was not associated with burnout. Approximately half of the respondents (n = 102; 51.5%) reported being satisfied with life as a resident. When controlling for common stressors, such as sleep deprivation, work-life measures associated with burnout included frequent perceived conflicts between personal and professional life (adjusted odds ratio, 4.35; 95% confidence interval, 1.91-9.88) and dissatisfaction with life as a resident (adjusted odds ratio, 11.74; 95% confidence interval, 4.23-32.57). CONCLUSION: Low relationship satisfaction and common work-life stressors were not associated with burnout among partnered pediatric residents. However, perceived work-life conflict and dissatisfaction with resident life were strongly associated with burnout and are targets for residency programs seeking to ameliorate burnout.
