Thyroid surgery in geriatric patients: a literature review.

BackgroundThyroid disease is common in the elderly population. The incidence of hypothyroidism and multinodular goitre gradually increases with age. In view of a growth of aging population, we performed a literature review about the feasibility of thyroid surgery in the elderly.MethodsWe conducted a literature search in the PubMed database in September 2012 and all English-language publications on thyroidectomy in geriatric patients since 2002 were retrieved. The potential original articles mainly focusing on thyroidectomy in elderly patients were all identified and full texts were obtained and reviewed for further hand data retrieving.ResultsWe retrieved five papers based on different primary end-point. Four were retrospective non randomized studies and one was prospective non randomized study. At last 65, 70, 75 and 80 years were used as an age cut-off. All studies evaluate the indications of thyroidectomy in geriatric patients, postoperative morbility and mortality. Only one study specifically assesses the rate of the rehospitalization after thyroidectomy among the elderly.ConclusionsThyroid nodules are particularly important in elderly patients, as the incidence of malignancy increases and they are usually more aggressive tumors. An age of at least 70 years is an independent risk factor for complications after general surgery procedures. Thyroid surgery in patients aged 70 years or older is safe and the relatively high rate of thyroid carcinoma and toxic goiter may justify an aggressive approach. A programmed operation with a careful pre-operative evaluation and a risk stratification should make the surgical procedures less hazardous, specially in 80 years old patients with an high ASA score.

Cytology-based gene mutation tests to predict response to anti-epidermal growth factor receptor therapy: A review

Recent therapeutic progresses in nonsmall cell lung cancer (NSCLC) and in colorectal cancer (CRC) are based on agents that specifically target the epidermal growth factor receptor (EGFR). To identify the patients most likely to benefit from such therapies, EGFR or KRAS gene mutation tests are mandatory, respectively, in NSCLC and in CRC. In patients with locally advanced or metastatic disease, exploiting cytological samples for these tests avoids not curative surgery. Here, we review the studies that have applied gene mutation assays on cytological samples of NSCLC and CRC to select patients for anti‐EGFR therapy. We argue that the standard of quality of gene mutation tests on cytological samples is closely dependent on the extent of the cytopathologists involvement. Diagn. Cytopathol. 2010.

Genetic mutations in the treatment of anaplastic thyroid cancer: a systematic review

BackgroundAnaplastic thyroid cancer (ATC) is a rare, lethal disease associated with a median survival of 6 months despite the best multidisciplinary care. Surgical resection is not curative in ATC patients, being often a palliative procedure. Multidisciplinary care may include surgery, loco-regional radiotherapy, and systemic therapy. Besides conventional chemotherapy, multi kinase-targeted inhibitors are emerging as novel therapeutic tools. The numerous molecular alteration detected in ATC are targets for these inhibitors. The aim of this review is to determine the prevalence of the major genetic alterations occurring in ATC and place the results in the context of the emerging kinase-targeted therapies.MethodsThe study is based on published PubMed studies addressing the prevalence of BRAF, RAS, PTEN, PI3KCA and TP53 mutations and RET rearrangements in ATC.Results21 articles dealing with 652 genetic analyses of the selected genes were used. The overall prevalence determined were the following: RET/PTC, 4%; BRAF, 23%; RAS, 60%; PTEN, 16%; PI3KCA, 24%; TP53, 48%. Genetic alterations are sometimes overlapping.ConclusionsMutations of BRAF, PTEN and PI3KCA genes are common in ATC, with RAS and TP53 being the most frequent. Given ATC genetic complexity, effective therapies may benefit from individualized therapeutic regimens in a multidisciplinary approach.

Cytologic, flow cytometry, and molecular assessment of lymphoid infiltrate in fine-needle cytology samples of Hashimoto thyroiditis

The thyroidal lymphoid infiltrate (TLI) in Hashimoto thyroiditis (HT) represents the substrate from which thyroid lymphoma may arise. The objective of the current study was to classify the TLI in HT by comparing the cytologic features with flow cytometry (FC) data and evaluating the κ/λ light chain ratio and its molecular assessment.

Cyclin D1 and D3 overexpression predicts malignant behavior in thyroid fine-needle aspirates suspicious for Hurthle cell neoplasms

Thyroid fine‐needle aspiration (FNA) samples that feature a follicular‐patterned, monotonous Hurthle (oncocytic) cell population cannot be diagnosed reliably. The authors of this report recently identified cyclin D3 overexpression on histologic sections of Hurthle cell carcinoma. In this study, they assessed the diagnostic value of cyclin D3 immunohistochemistry added to routine cytology.

Fine needle aspiration cytology of medullary thyroid carcinoma: a review of 18 cases

A series of 18 consecutive medullary thyroid carcinomas (MTC) diagnosed by fine needle aspiration cytology (FNAC) is described. The most important diagnostic cytologic criteria were the dispersed cell pattern, the polygonal appearance of the cells, binucleated cells and the presence of amyloid. Other less common cytologic features are reported and the variable microscopic appearance of MTC is pointed out. The possibility that this cytologic variability of MTC may be by itself an important diagnostic feature is proposed.

Hodgkin's disease: diagnostic accuracy of fine needle aspiration; a report based on 62 consecutive cases

We report on our series of 62 cases occurring between January 1977 and December 1990, which were diagnosed as Hodgkins disease by fine needle aspiration (FNA) samples. the overall accuracy of the cytological diagnosis was high, with only four incorrect diagnoses and a positive predictive value of 93.5%. the value of FNA as a first level diagnostic technique in the screening of lymphadenopathies is discussed, as well as the limitations and pitfalls of the cytological diagnosis.

Acinic cell carcinoma arising in a lacrimal gland. First case report

Acinic cell carcinoma is a rare neoplasm nearly always observed in the salivary glands. Our experience documents a case of this pathology, occurring in the lacrimal gland, never reported in the literature before. A 59‐year‐old white woman was admitted with reduced vision and a painless swelling in the area of the right lacrimal gland. Computerized axial tomography showed an intraorbital radio‐opaque mass compressing the eyeball from behind. The patient underwent right temporal orbitotomy and total removal of the lesion. The surgical specimen was constituted by a cystic mass containing citrine liquid. Microscopic examination proved the lesion to be an acinic cell carcinoma. Differential diagnostic problems and similarity to salivary gland acinic tumors are discussed.
