Impact of age on central lymph nodes involvement in papillary thyroid cancer.

BACKGROUND: Total thyroidectomy is the main line of treatment for papillary thyroid cancer. Central lymph node dissection (CLND) is still debatable. In this study, we aimed to correlate the central lymph node status with the age of patients. METHODS: This is a retrospective study including patients with papillary thyroid cancer (PTC) who underwent total thyroidectomy and CLND at a tertiary cancer center during the period from January 2012 to September 2022. Patients were subdivided into 3groups: patients younger than 20 years old, patients between 20 and 40 years old, and patients older than 40 years old. Correlation between central lymph node status, lateral lymph node status, and harvest count with each other and between age groups was done. RESULTS: 315 patients were included. The younger the age group the higher the possibility of harboring positive central nodes, however, the positivity of lateral nodes was similar. Neither central nodal harvest nor positive central node count significantly differed between groups. The lateral nodal harvest was significantly higher in the < 20 years group with no affection to the number of positive nodes retrieved. The younger the age group the longer the disease-free survival (DFS). CONCLUSION: We can conclude that patients younger than twenty years had a higher probability of harboring malignancy in central nodes and higher lateral node harvest on dissection. In contrast, they do have a lower incidence of recurrence.

Shifting Epidemiology Trends in Tongue Cancer: A Retrospective Cohort Study.

The tongue is the most common site for oral cavity carcinoma. It typically has male predominance. However, several studies have documented an increasing number of incidences among the younger population, with female predominance, which is unusual. In this study, we aimed to determine current trends in tongue cancer regarding age and gender. Data from 197 tongue cancer patients were extracted from The Oncology Center, Mansoura University (OCMU) database from 2006 to 2021. The patients were divided into two time periods: (2006-2013) and (2014-2021). We computed counts and proportions of tongue cancer for demographic and tumor characteristics. The data were analyzed using SPSS. Gender showed no statistically significant difference in both groups, while the percentages of diagnosed females were 52.7% and 52%, respectively. The percentages of males were 47.3% and 48%, p-value = 0.927. There was a statistically significant difference in the number of patients aged 20 to 39 years old and ≥60 years old in both periods. The p-values were 0.039 and 0.011, respectively. Although tongue cancer is typically more common in males, our results showed no significant difference in the gender of diagnosed patients. In addition, our results showed that the number of younger patients significantly increased in the period from 2014 to 2021. However, we encourage further investigations involving larger populations.

A Cervical Thymic Cyst in an Adult Female; A Case Report and Comprehensive Literature Review.

Introduction: Cervical thymic cyst accounts for (0.3-1) % of cervical cysts in children and are usually present during the first decade of life with few reported cases in adults. Herein, we present a 34-year-old female with a cervical thymic cyst. We conducted a review of all the previously reported cases as well. Case presentation: The patient complained of an anterolateral neck swelling that was noticed one year ago. It was a soft, fluctuant, mobile, non-tender swelling in the midline and the right side of the lower neck. Neck ultrasonography revealed a large thin-walled cyst, with no internal septa, echoes, or solid parts. Post-contrast MRI of the neck showed a well-defined, oblong-shaped, lobulated cystic lesion just beneath the strap muscle. The cyst extended caudally to the superior border of the anterior mediastinum at the level of the upper border of the manubrium sterni. The patient underwent excision of the swelling under general anesthesia via Kocher's collar neck incision. Connection with the thymus gland was detected behind the manubrium sterni which was separated. Pathological examination showed prominent thymic tissue confirming the diagnosis of a cervical thymic cyst. Conclusion: Adult cervical thymic cyst is very rare with a few cases reported in the literature. Surgical excision in symptomatic patients is the treatment of choice. Paper's main novel aspects: • A rare presentation of a cervical thymic cyst in an adult. • A comprehensive literature review including all the previously reported cases in one table.

Effect of non-invasive follicular thyroid neoplasm with papillary-like features (NIFTP) terminology on surgical management concepts.

BACKGROUND: Despite the strict diagnostic criteria recently proposed for non-invasive follicular thyroid neoplasm with papillary-like features (NIFTP), its incidence is still unknown. Employing a retrospective analysis of the follicular variant of papillary thyroid carcinoma (FVPTC), we investigated the diagnosis, prevalence and postoperative course of NIFTP. METHODS: We examined retrospectively the records of 112 patients who had undergone thyroid surgery and had a postoperative diagnosis of FVPTC at our hospital from 2010 to 2021. All clinical, radiologic, and pathologic features were evaluated. RESULTS: Only 34 (27.9%) patients met the strict pathologic criteria for NIFTP; 11 cases having been diagnosed as NIFTP initially and 23 after re-evaluation of histopathologic slides. None of the 11 NIFTP patients underwent a 2-stage operation, in contrast to 10 (29.4%) patients initially diagnosed as FVPTC who had a completion thyroidectomy after the initial hemithyroidectomy. The median follow-up was 14.5 (ranging from 0 to 78) months. None of the cases developed a recurrence. CONCLUSION: To avoid unnecessary treatment or the follow-up advised for papillary thyroid carcinoma, clinicians and pathologists should be familiar with the terminology and the corresponding diagnostic criteria for NIFTP and their impact on management.

Fungating and Ulcerating Breast Cancer: Wound Closure Algorithm, Complications, and Survival Trends.

Fungating breast cancer severely affects patients' daily lives, and patient management poses major oncology challenges. To present 10-year outcomes of unique tumor presentation, suggesting a focused algorithm for surgical management and providing deep analysis for factors affecting survival and surgical outcomes. Eighty-two patients with fungating breast cancer were enrolled in the period from January 2010 to February 2020 in the Mansoura University Oncology Center database. Epidemiological and pathological characteristics, risk factors, different surgical treatment techniques, and surgical and oncological outcomes were reviewed. Preoperative systemic therapy was used in 41 patients, with the majority (77.8%) showing progressive response. Mastectomy was performed in 81 (98.8%) patients, with primary wound closure in 71 (86.6%), and wide local excision in a single patient (1.2%). Different reconstructive techniques in non-primary closure operations were used. Complications were reported in 33 (40.7%) patients, of which 16 (48.5%) were of Clavien-Dindo grade II category. Loco-regional recurrence occurred in 20.7% of patients. The mortality rate during follow-up was 31.7% (n = 26). Estimated mean overall survival (with 95% CI) was 55.96 (41.98-69.9) months; estimated mean loco-regional recurrence-free survival (with 95% CI) was 38.01 (24.6-51.4) months. Surgery is a cornerstone fungating breast cancer treatment option, but at the expense of high morbidity. Sophisticated reconstructive procedures may be indicated for wound closure. A suggested algorithm based on the center's experience of wound management in difficult mastectomy cases is displayed.

Multidetector computed tomography (MDCT) angiography in the evaluation of external carotid artery.

BACKGROUND: Knowledge about anatomical variants of the external carotid artery is crucial in head and neck surgery and interventional technique. This work aimed to present the frequency of regular and another variant of the external carotid artery using 128 multidetector computed tomography (MDCT) angiography. MATERIALS AND METHODS: This retrospective study included 120 patients in our university hospital between April 2017 and October 2021. They were 65 men and 55 women (mean age, 45.6 years; range, 18-65 years). They were angiofibroma (10 patients), cerebral stroke (28 patients), partial glossectomy (13 patients), submandibular gland excision (12 patients), parotidectomy (17 patients), mandibulectomy (5 patients), and a thyroidectomy (35 patients). We retrospectively analyzed the level and branches of external carotid arteries on both sides of 120 patients. RESULTS: According to the level of bifurcation; the external carotid artery originated at the level of the upper border of the thyroid cartilage in 164/240 cases (68.3%), and a higher level was detected in 76/ 240 cases (31.7%). The lower level of origin of the external carotid artery was not detected. The superior thyroid, facial, and lingual arteries originated from separate branches of external carotid arteries in 173/240 cases (72.1%). At the same time, the facial arteries originated with lingual arteries in a common trunk in 67/240 cases (27.9%). CONCLUSION: MDCT angiography is a valuable noninvasive diagnostic tool for evaluating the external carotid artery and its branches.

Impact of Morbid Obesity on the Outcomes of Type II Endometrial Cancer: a Cohort Study.

Obesity has long been associated with endometrial cancer. However, there is a paucity of studies addressing the impact of morbid obesity in type II endometrial cancer on oncologic and surgical outcomes. In this study, the author retrospectively compared morbid to non-morbid obese in clinico-epidemiologic, surgical, and oncologic outcomes. Both groups were comparable as regards all clinico-epidemiologic parameters. Vaginal involvement, survival, and recurrence were also comparable between the 2 groups. Para-aortic adenopathy and treatment with preoperative therapy were the only significant predictors of DFS. Surgery is feasible with equivalent complications and oncologic outcomes in morbidly obese patients with type II endometrial cancer.

Primary thyroid chondrosarcoma: a case report of an extremely rare malignancy.

INTRODUCTION: There are different types of malignant tumors that can affect the thyroid gland where differentiated thyroid carcinomas (papillary and follicular) are the most common representing nearly 90% of cases. Non-epithelial malignancies were also reported to affect the thyroid gland particularly lymphomas and sarcomas that were reported in literature to range from 0.01 to 1.5% of thyroid carcinoma. Herein, we present a case with primary thyroid chondrosarcoma, an extremely rare malignancy of the thyroid gland. CASE PRESENTATION: We present a 79-year-old female patient complaining of hard thyroid swelling that was proved to be primary thyroid chondrosarcoma after histopathological assessment. CONCLUSION: Chondrosarcoma of the thyroid gland is extremely rare either in the primary or metastatic setting. Although the prognosis is bad, surgery is the main line of treatment after early prompt diagnosis.

Brain metastatic breast cancer: Epidemiology, survival and prognosis: Single center experience / Cáncer de mama metastásico cerebral: epidemiología, supervivencia y pronóstico; experiencia en un solo centro

Introduction Breast carcinoma is the most common malignancy in women worldwide. It is also one of the most frequent causes of brain metastasis (BM). Studies have identified BM as one of the worst prognostic signs. Methods We retrospectively analyzed data from 71 patients with BM from BC with the aim of clarifying the epidemiological criteria and management in our setting. We also aimed to identify predictors of survival and factors affecting the length of the BM-free interval in our group of patients. Results All the patients were female with a mean age at diagnosis of primary cancer of 41.6 years. The most common site of BM was the parietal lobe. The BM-free interval was longer with N1 disease (in comparison to N2 and 3) and in luminal B breast cancer subtype. Survival was shorter in older patients, those with hormone receptor negative and/or HER2-neu positive disease, synchronous BM, primary tumour not removed, soft tissue/non-regional nodes concomitant metastasis, and those who did not receive palliative chemotherapy. Survival tended to be longer in patients with temporal lobe metastasis, but this result was not statistically significant. Conclusion BM is a bad prognostic sign. Large scale prospective studies are needed to further delineate its nature. (AU)

Introducción El carcinoma de mama es la neoplasia maligna más común en las mujeres del mundo. Además, es una de las causas más comunes de metástasis cerebral (MC). Los estudios detectan MC como uno de los peores signos pronósticos. Métodos Analizamos retrospectivamente los datos de 71 pacientes con MC de origen mamario con el objetivo de clarificar los criterios epidemiológicos y el esquema de manejo en nuestra localidad de esta enfermedad, además de detectar predictores de supervivencia y factores que afectan la longitud del intervalo libre de MC en nuestro grupo de pacientes. Resultados Todos los pacientes fueron mujeres con una edad media de diagnóstico de cáncer primario de 41,6 años. El sitio más común de MC fue el lóbulo parietal. El intervalo libre de propagación cerebral fue más largo con la enfermedad N1 (en comparación con N2 y 3) y en el subtipo de cáncer de mama luminal B. La supervivencia fue menor en pacientes mayores, aquellos con receptores hormonales negativos y/o enfermedad HER2-neu positiva, MC sincrónica, tumor primario no extirpado, metástasis concomitantes de tejido blando nodos no regionales y aquellos que no recibieron quimioterapia paliativa. Además, aquellos con metástasis del lóbulo temporal tienden a tener una mejor supervivencia, aunque no alcanzaron significación estadística. Conclusión La MC es un mal signo pronóstico. Se necesitan estudios prospectivos a gran escala para delinear aún más su naturaleza. (AU)

Renovating the Old Fashion: The "Functional Technique" for Harvesting Pectoralis Major Muscle Flap in Head and Neck Reconstruction.

Although free flaps are widely recognized as a gold standard, pectoralis major muscle flap (PMMF) still remains a valuable workhorse in head and neck reconstruction. The technique we describe in the present paper allows to harvesting the PMMF with an accurate and complete isolation of the pedicle, sparing the superior sternum-acromion muscular fibers.

Thyroid cancer associated with Hashimoto thyroiditis: similarities and differences in an endemic area.

BACKGROUND: Hashimoto thyroiditis (HT) is an autoimmune lymphocytic thyroiditis and is the most common form of thyroid inflammatory diseases. The association of HT with papillary thyroid carcinoma (PTC) has been described. PTC is the most common form of malignancy associated with HT. When papillary carcinoma develops on top of Hashimoto thyroiditis, the disease tends to be less aggressive and lymph node and extra-thyroidal invasion are infrequent. RESULTS: We retrospectively examined the pathological features of our patients who were diagnosed with concomitant HT and thyroid cancer. In Egyptian patients, PTC was the main type of malignancy associated with HT (96.2%) and was often multifocal (46.2%). In contrast to the published literature, lymph node invasion and extra-thyroidal extension were as frequent in association with HT as in other cancer cohorts. We also observed the frequent occurrence of Hürthle cell metaplasia (23.1%) and the appreciable incidence of aggressive histological types of PTC (32%). CONCLUSION: Thyroid carcinoma with HT may have some aggressive features in areas with endemic goiter background.

Recurrent mandibular ameloblastoma in soft tissue and rib graft 17 years after initial presentation.

BACKGROUND: Ameloblastoma is the commonest odontogenic tumour of epithelial origin with a high incidence for developing local recurrence. We present a patient who developed local recurrence in both soft tissue and bone graft 17 years after the initial presentation. CASE PRESENTATION: A 75-year-old female with a previous history of right hemimandibulectomy and rib reconstruction for ameloblastoma in 1999 presented to our centre with a large cystic mouth floor swelling, biopsy from which revealed recurrent ameloblastoma. The patient underwent excision of the recurrent mass en bloc with the cystic swelling through oral and cervical approaches. The patient was discharged after 5 days with an uneventful postoperative course and with a free 2-year follow-up from further recurrence. CONCLUSION: Ameloblastoma is a locally aggressive tumour for which wide local excision with adequate margins is the best management approach. Recurrence of ameloblastoma even after adequate resection is not uncommon, and its management is considered a surgical challenge. A very long time may pass between the initial presentation and the development of recurrence.

Anatomically-based transoral surgical approach to early-stage oral tongue squamous cell carcinoma.

The mainstream of treatment of early-stage oral tongue squamous cell carcinoma (OTSCC) is represented by transoral resection with "adequate" free margins. Despite that, a precise and shared definition of "adequate margin" is lacking, and so is a standardized transoral surgical technique.The tongue is a symmetrically paired organ, consisting of intertwining intrinsic and extrinsic muscles, which can be distinguished during dissection. Routes of tumoral spread in oral tongue cancer are well-known and should be taken into account during resection. We propose herein a standardized and replicable surgical technique to resect early-stage OTSCC, based on rational anatomical considerations.

Gigantic submandibular pleomorphic adenoma: A rare case report.

INTRODUCTION: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor. When neglected on some occasions, its size and weight can enormously augment. CASE PRESENTATION: We report a case of a giant submandibular pleomorphic adenoma in a 75 years old female patient which measured 34 × 26 × 20 cm and weighed 8.1 kg. CONCLUSION: Neglecting such tumors without treatment, can cause severe facial disfigurement and can even hinder the airway.

Role of P53, E-cadherin and BRAF as predictors of regional nodal recurrence for papillary thyroid cancer.

BACKGROUND: Regional nodal recurrence (RNR) in patients diagnosed with papillary thyroid carcinoma (PTC) has increased. Variable immunohistochemical (IHC) markers have been studied for predicting the likelihood of PTC for recurrence. We aimed to clarify the IHC expression of p53, Ecadherin and BRAF as potential markers of RNR in PTC. METHOD: 145 (73 study group and 72 control group) patients with PTC were analyzed retrospectively between January 2010 and June 2017. Further classification to a specific histological variant was done, and IHC expression of p53, Ecadherin and BRAF was analyzed both in the primary tumor and in nodal recurrence. RESULTS: Regarding the risk of RNR, we found certain clinicopathologic features as elder age ≥55 years, tumor size >1 cm, presence of microscopic extrathyroid extension, presence of lymphovascular emboli, and conventional papillary subtype. Furthermore, IHC results for negative E-cadherin, and positive P53 and BRAF are significant risk factors, while radioactive iodine (RAI) adjuvant therapy decrease recurrence risk. CONCLUSION: We found several risk factors for RNR in PTC diagnosed patients, all of which are easily achievable in clinical settings. In this regard, we suggested that patients with specific clinicopathologic and immunohistochemical features have strict follow up for early detection of RNR as it has a great impact on their survival.

Primary desmoplastic small-round-cell tumor of the ovary.

BACKGROUND: Desmoplastic small-round-cell tumor (DSRCT) is an extremely rare and highly aggressive malignancy. It is of yet unclear origin, but it is assumed to be of a mesothelial origin based on its tendency for widespread metastasis in serosal linings. CASE PRESENTATION: In this report, we describe a young female who presented with bilateral ovarian masses that mimicked the classic clinical picture of ovarian cancer. The patient had a cytoreductive surgery done in the form of total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic peritonectomy, low para-aortic and bilateral iliac lymphadenectomy. Postoperative course was smooth with no adverse events. The final pathology report revealed desmoplastic small-round-cell tumor. Afterwards, the patient was referred to medical oncologist to receive her adjuvant therapy. CONCLUSIONS: DSRCT is still an unknown disease to us given the limited number of cases and poor survival. Given the lack of clear guidelines, treatment is offered based on the best available evidence and the collaborative effort of a multi-disciplinary team.

Primary ovarian carcinoid: A report of two cases and a decade registry.

OBJECTIVES: This study aims at reporting 2 cases of primary ovarian carcinoid tumor, and providing an adequate registry of such cases and how they were managed. METHODS: 2 female patients with primary ovarian carcinoid were diagnosed and treated in our center. Discussion of their presentation, pathology and treatment is entitled. Also a thorough search of all published registries and case reports of ovarian carcinoid was done with analysis of reported data. RESULTS: 164 cases of primary ovarian carcinoid tumor were detected since 2005 with the predominance of the insular variant. Carcinoid syndrome occurs in nearly 14% of these cases. Most of the cases were treated with hysterectomy. Unfortunately, the prognosis was not documented in most series. CONCLUSION: Primary ovarian carcinoid is a relatively rare disease with an indolent course and excellent outcome. Carcinoid syndrome, especially carcinoid heart disease may worsen the prognosis. Total abdominal hysterectomy with bilateral salpingo-oophorectomy has been commonly used as the treatment of choice of primary ovarian carcinoid tumors.

Meckel's diverticulum complicated with gastro-intestinal stromal tumor: Case report.

INTRODUCTION: Meckel's diverticulum is a common congenital anomaly, mostly asymptomatic. Tumors may arise rarely in these diverticulae. We claim presenting a new problem to the medical staff in Egypt. CASE PRESENTATION: We report a case of a 49year old male patient who attended our center with pelvic mass insinuated between the bladder and the rectum. On exploration the mass was found arising at the tip of a Meckel's diverticulum, Gastro-intestinal stromal tumor (GIST) was confirmed by pathology. DISCUSSION: In review of recently published cases most of these tumors were presented with vague abdominal pain as in our case. Tumors were treated by resection with or without adjuvant Imatinib. CONCLUSION: Surgeons and oncologists should bear in mind this rare diagnosis and know how to treat it.
