Continuous development of oncology as a science in the last decades and years led to noticeable improvement in treatment outcomes for patients with various malignant tumors. Diagnostics, surgery, radiotherapy significantly contributed to this improvement, however they cannot be compared to the progress achieved through advancements in our knowledge of genetic structure of tumors and subsequent advancements in pharmacology which allowed to achieve qualitatively better survival in oncological patients. These advancements did not leave out such a serious and highly lethal, though fortunately rare, disease as anaplastic thyroid cancer. This article is dedicated to the possibilities of using checkpoint inhibitors in treatment of this pathology to increase expected life span of the patients.

More than 90 % of newly diagnosed cases of endocrine cancer occur in the thyroid gland. Introduction of fine needle puncture of the thyroid gland, with the classification of cytological material according to the Bethesda system, has become the cornerstone of the diagnosis of malignant neoplasms of the thyroid gland. However, traditionally in this classification there remains a weak link called a follicular tumor (category IV). The detection of a follicular tumor in the cytological material does not allow one to reliably classify the mass as benign or malignant and requires surgical intervention with morphological verification. In recent years, the possibilities of molecular genetic testing have improved markedly. Follicular tumors tend to accumulate mutations, which over time can lead to malignant transformation, but can also be used as a method of timely diagnosis. This review analyzes the literature on the possibilities of molecular genetic testing in assessing the malignant potential of follicular formations of the thyroid gland.

Introduction. Cutaneous melanoma is one of the most aggressive malignant tumors, and its nodular form with vertical growth is characterized by unfavorable prognosis. However, in the recent years due to advances in basic oncology, a breakthrough in drug therapy of this pathology was made. To a great extent, it is linked to implementation of new therapy with checkpoint inhibitors. The best and longest response rates of cutaneous melanoma to this treatment were achieved compared to other oncological diseases. This fact can be explained by immunogenicity of cutaneous melanoma, high mutational load, as well as features of its tumor microenvironment, where in most cases high infiltration by immunocompetent cell is observed. However, immune cells vary by their composition and functions. Some of them can even promote tumor growth. Therefore, study of cell composition, degree and distribution of immune infiltration in the tumor can help identify potential factors of favorable and unfavorable prognosis for cutaneous melanoma which is important in clinical practice.Aim. To determine the frequency of CD3+-, CD4+-, CD8+-T-lymphocytes, CD163, BCL6 and SOX10 expression in patients with primary nodular cutaneous melanoma, as well as correlation of these markers with each other and standard morphological parameters for this non-epithelial malignant tumor.Materials and methods. In the study, the expression frequency of CD3+-, CD4+-, CD8+-T-lymphocytes, CD163, BCL6 and SOX10 in the postoperative material of 20 patients with true primary nodular cutaneous melanoma was measured using immunohistological analysis. The correlation of these markers with each other and standard morphological parameters was determined.Results. In most cases of nodular cutaneous melanoma, moderate and marked lymphocytic (immune) infiltration (grade II–III) was observed with no correlation with Breslow tumor thickness. Study of the ratio between CD4-positive T helpers and CD8-positive cytotoxic T lymphocytes in the tumor microenvironment showed that the number of the latter increased the higher was the degree of immune infiltrate. Markedness of macrophage infiltration directly correlated with markedness of lymphocytic infiltration. BCL6 expression in lymphocytes was observed in all cases of infiltration.Conclusion. Immune infiltrate in nodular cutaneous melanoma is a multicomponent, dynamic microenvironment containing both antitumor and tumor-promoting components with balance shifting to one or other side. Their qualitative, quantitative and, possibly, topographic ratios in the primary lesion of cutaneous melanoma affect the effectiveness of drugs and disease prognosis. Knowledge on the predominance of components negatively affecting tumor growth in the primary lesion can help an oncologist in selection of correct treatment tactics and disease observation.

Intrоduction. Sinonasal papilloma is a benign tumor. The standard treatment for sinonasal inverted papilloma (SIP) is surgical intervention. The tumor is located primarily in the maxillary sinus (50.9 %). Sinonasal inverted papilloma originated from the maxillary sinus has aggressive characteristics and can dislodge local anatomical structures, infraorbital canal in particular.Aim. To present a descriptive characteristic of structural changes in the infraorbital canal during SIP growth and determine the optimal volume of canal dissection.Materials and methods. A retrospective study of patients with SIP was performed. From the total cohort (n = 37), 15 patients with primary localization of sinonasal inverted papilloma in the maxillary sinus were selected. In all cases, the same diagnostic algorithm was used. Separately, evaluation of infraorbital canal anatomy based on preoperative analysis of computed tomography of the paranasal sinuses and intraoperative endoscopic exam was performed. Surgical strategy used in all cases consisted of endoscopic SIP tissue removal, total resection of the mucoperiosteum and subperiosteal dissection of all walls of the maxillary sinus using a bur. During surgery material was collected for control histological examination.Results. In 20 % of cases, changes in the walls of the infraorbital canal in the form of hyperostosis, erosion and dehiscence were observed. In 13.3 % of cases, growth of sinonasal inverted papilloma caused distortions in the structure of infraorbital canal walls. In all cases, computed tomography data showed the same results as intraoperative endoscopic visualization. For removal of the lesion and pathologically changed walls of the infraorbital canal, transnasal endoscopic partial maxillectomies (type 3 or 4) were performed. Follow-up duration varied between 1 and 5 years, mean follow-up duration was 3 years. SIP resection was effective in all patients, no recurrences were observed.Conclusion. For SIPs growing in the maxillary sinus, condition of the infraorbital canal must be of special interest. The study showed the effectiveness and flexibility of the surgical strategy consisting of the combination of total mucoperiosteum resection with subperiosteal dissection of all walls of the maxillary sinus.

Introduction. Squamous cell carcinoma of the oral mucosa advances into the mandible in locally advanced tumors in 13–38 % of cases. Frequently, this situation requires inclusion of segmental resection of the mandible into the surgical plan. This approach requires adequate reconstruction for preservation of satisfactory functional and esthetic treatment results. Selection of reconstruction method remains an important clinical problem in everyday practice of a head and neck cancer specialist.Aim. To analyze clinical materials on the use of reconstruction plates in oncological practice, evaluate esthetic and functional results of their use in patients who underwent single-stage reconstruction after segmental resection of the mandible.Materials and methods. The results of treatment of 103 patients after segmental resection of the mandible with defect reconstruction using only a reconstruction plate or a reconstruction plate with a distant or free flap who were treated at the Loginov Moscow Clinical Scientific Center and N.N. Blokhin Scientific Medical Research Center of Oncology between 1998 and 2019 were analyzed.Results. Complications at various times (between 2 months and 3 years) were observed in 15 (14.6 %) patients. The most frequent complications were plate cutting through the skin and mucosa (6 (5.8 %) cases) and osteomyelitis of fragments of the mandible (7 (6.7 %) cases). In 2 (1.9 %) cases, plate fracture was observed. It is necessary to note that during anti-inflammatory treatment in 4 (3.9 %) patients, osteomyelitis was managed while 11 (10.7 %) patients required removal of the reconstruction plate. Per the data analysis, in patents with surgical defect in the anterior area (defects ТТ, АТТ, САТ per the J.S. Brown classification, 2016) complications are significantly more common (in 11 (23.9 %) of 46 cases) than in patients with limited defects of the body and condyle (defects АТ, АС) (in 4 (7.0 %) of 57 cases). The rate of complications is also significantly affected by radiation dose.Conclusion. Therefore, use of a plate for reconstruction of mandible defect is aesthetically and functionally acceptable reconstruction technique. Severe complications leading to plate removal are rare and were observed in 11 (10.7 %) patients.

Introduction. Incidence of brain metastases rises in recent years. Local control after surgical resection of brain metastases is a priority for patients with limited intracranial disease and controlled primary tumor. Surgery should be combined with other methods because of the high risk of local recurrences.Aim. To analyze the overall survival (OS) and influencing factors for patients with brain metastasis after combined therapy. Materials and methods. The retrospective study included 196 patients with stable systemic cancer or available systemic therapy in cases of progressive disease. All patients had from 1 to 3 brain metastasis. Overall survival and influencing factors after surgical and combined therapy were analysed.Results. Median OS for the entire cohort was 16.9 months. The highest levels of OS were achieved for patients with renal cancer (median OS 32.5 months). For patients with non-small cell lung cancer, breast cancer, melanoma and other cancers OS were 18.8; 19.9; 11.0 and 15.3 months, appropriately. Age, continuation of local therapy in brain (surgical intervention, stereotactic radiosurgery), using of the cisplatin for patients with non-small lung cancer brain metastasis were independent factors that have influenced OS.Conclusion. Application of combined therapy for brain metastasis can provide reasonable OS for patients with controlled systemic disease. Using of the cisplatin as a part of combined therapy provide statistically meaningful rise in OS for patients with non-small lung cancer brain metastasis.

Introduction. Measurement of thyroglobulin (Tg) in a washout after fine-needle aspiration (FNA) is recommended for the diagnosis of metastases of differentiated thyroid cancer (DTC), but the method is not standardized and there is no recommended threshold value of Tg washout, which makes it difficult to interpret the results.Aim. To analyze Tg in the washout after FNA of lesions of different origin on the neck and to determine its optimal cutoff for the diagnosis of DTC metastases.Materials and methods. Ultrasound-guided FNA was performed in 1258 neck masses from 591 patients, 566 of them with confirmed DTC. In 1023 lesions, FNA was performed after thyroidectomy, 22 – after lobectomy, 213 – with preserved thyroid gland. The needle after FNA was washed in 1 ml of saline, in which the concentration of Tg was then examined. The level of Tg in the washout was compared with the histological (n = 522) or cytological diagnosis if no surgery was performed. The cut-off for Tg washout was determined by ROC analysis.Results. DTC lymph node metastases detected in 577 specimens. Nine specimens were obtained from metastases of thyroid cancer (TC) that does not express Tg (anaplastic TC, poorly differentiated TC, columnar-cell variant DTC), 22 – from neck metastases of other malignancy (lung cancer, mucinous soft tissues tumor, ovarian cancer, esophageal cancer, melanoma, neuroendocrine tumor), 6 – from other tumors of the neck (lymphoma, parathyroid adenoma, neurinoma). In 26 cases, the specimen was regarded as normal thyroid tissue left after thyroidectomy, 37 – postoperative seroma or granuloma, 1 – cyst of the neck, 578 – lymph node hyperplasia, 2 – sarcoidosis. The level of Tg washout from DTC metastasis and thyroid remnant significantly differed from that of non-thyroidal origin (p <0.0001). At the cut-off of 7.8 ng/ml, the sensitivity and specificity of Tg washout in the diagnosis of DTC metastases is 94 and 95 %, and at the cut-off of 20 ng/ml, 90 and 98 %, respectively. False-negative results were obtained from DTC with squamous metaplasia or sparse tumor cells in a specimen. False-positive results were obtained more often from lesions of level VI and IV compared with other localizations (8 % versus 4 %; p = 0.04). There were no differences in false positive rate in patients before and after thyroidectomy (p = 0.17), but in patients after thyroidectomy with a serum Tg >200 ng/ml, the false positive rate of Tg washout was significantly higher than that with a lower level of serum Tg (28 % versus 3 %; p = 0.0004). When comparing diagnostic performance of cytology and Tg washout, the advantage of the latter is in the diagnosis of cystic metastases, and the former is in the diagnosis of micrometastases and tumors that do not express Tg. Thyroglobulin in the washout increased the sensitivity of the cytology by 8 %. The combined use of these methods detected DTC metastases in 100 % of patients.Conclusion. Measurement of Tg in the washout is a useful addition

The needle after FNA was washed in 1 ml of saline, in which the concentration of Tg was then examined. The level of Tg in the washout was compared with the histological (n = 522) or cytological diagnosis if no surgery was performed. The cut-off for Tg washout was determined by ROC analysis.Results. DTC lymph node metastases detected in 577 specimens. Nine specimens were obtained from metastases of thyroid cancer (TC) that does not express Tg (anaplastic TC, poorly differentiated TC, columnar-cell variant DTC), 22 – from neck metastases of other malignancy (lung cancer, mucinous soft tissues tumor, ovarian cancer, esophageal cancer, melanoma, neuroendocrine tumor), 6 – from other tumors of the neck (lymphoma, parathyroid adenoma, neurinoma). In 26 cases, the specimen was regarded as normal thyroid tissue left after thyroidectomy, 37 – postoperative seroma or granuloma, 1 – cyst of the neck, 578 – lymph node hyperplasia, 2 – sarcoidosis. The level of Tg washout from DTC metastasis and thyroid remnant significantly differed from that of non-thyroidal origin (p <0.0001). At the cut-off of 7.8 ng/ml, the sensitivity and specificity of Tg washout in the diagnosis of DTC metastases is 94 and 95 %, and at the cut-off of 20 ng/ml, 90 and 98 %, respectively. False-negative results were obtained from DTC with squamous metaplasia or sparse tumor cells in a specimen. False-positive results were obtained more often from lesions of level VI and IV compared with other localizations (8 % versus 4 %; p = 0.04). There were no differences in false positive rate in patients before and after thyroidectomy (p = 0.17), but in patients after thyroidectomy with a serum Tg >200 ng/ml, the false positive rate of Tg washout was significantly higher than that with a lower level of serum Tg (28 % versus 3 %; p = 0.0004). When comparing diagnostic performance of cytology and Tg washout, the advantage of the latter is in the diagnosis of cystic metastases, and the former is in the diagnosis of micrometastases and tumors that do not express Tg. Thyroglobulin in the washout increased the sensitivity of the cytology by 8 %. The combined use of these methods detected DTC metastases in 100 % of patients.Conclusion. Measurement of Tg in the washout is a useful addition","PeriodicalId":12937,"journal":{"name":"Head and neck tumors (HNT)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87281363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salivary gland carcinomas is a rare family of neoplasms with different histological characteristics and biological behavior. Treatment regimens have remained virtually unchanged for decades, leaving the leading role for surgical treatment and radiation therapy. However, a special place in the salivary gland carcinomas group is occupied by adenoid cystic carcinoma, which is quite often characterized by a recurrent and / or metastatic course with the use of chemotherapy as the main option in treatment. It is worth noting the fact that the results of standard chemotherapy regimens show unsatisfactory results, respectively, with recurrent or metastatic adenoid cystic carcinoma, treatment options are minimal. Accordingly, there is a need to study new therapeutic methods for the treatment of this disease. In this situation, high hopes were placed on targeted therapy, in particular, the family of epidermal growth factor receptors, c-Kit are the most frequently studied molecular targets. Due to the rare occurrence of adenoid cystic carcinoma, the number of cases of using targeted therapy for analysis is relatively small, so each clinical observation is of particular value. The following is a clinical case of treatment of recurrent adenoid cystic carcinoma using a personalized treatment approach.Aim. To describe the clinical observation of the use of targeted drugs in recurrent or metastatic adenocystic cancer of the salivary glands.

Clinical cases of distant metastasis of basal cell skin cancer are extremely rarely described in the international publications. This is probably due to the specific locally advanced growth of this histological type of tumor, as well as to the improvement of radical treatment methods for this group of patients. However, despite the development of both diagnostic research methods and treatment tactics, a large number of patients, especially when the primary tumor is located on the face and neck region, choose less effective and not always radical methods of treatment. In turn, non-radical removal of the primary tumor leads not only to difficulties in local control of the disease, but also to lymphogenous, as well as hematogenous spread of tumor cells and the manifestation of systemic metastasis.In the article, we present a clinical case of metastatic basal cell skin carcinoma of the periorbital region with lesions of the bones of the skeleton, namely the thoracic vertebrae manifested 11 years after the detection of the primary tumor.

Introduction. Papillary thyroid carcinoma is the most common subtype of thyroid cancer as it comprises 95 % of cases. Frequently, this pathology develops in the presence of autoimmune thyroiditis (Hashimoto’s thyroiditis) which is the main cause of hypothyroidism in various rich in iodine regions. Papillary thyroid carcinoma is characterized by good prognosis, however some patients experience recurrence which depends on the volume of surgical intervention.Aim. To compare clinical outcomes and complications after hemithyroidectomy (HE) and thyroidectomy (TE) in patients with papillary thyroid carcinoma secondary to autoimmune thyroiditis.Materials and methods. The retrospective study included 2031 patients with papillary thyroid carcinoma. Considering individual risk factors, 67 patients were excluded from the HE group, and 588 patients were excluded from the TE group. Each group included 688 patients for whom data were matched. Such individual factors as age, sex, primary tumor size, extrathyroidal invasion, multifocal tumor and cervical lymph node metastasis were taken into account.Results. During 10‑year follow-up, recurrence was diagnosed in 26 (3.8 %) patients of the HE group and 11 (1.6 %) patients of the TE group. Relative risk of recurrence was significantly lower after TE than after HE (risk ratio (RR) 0.41; 95 % confidence interval (CI) 0.21–0.81; р = 0.01). In the HE group, for the majority of patients recurrence was observed in the contralateral lobe of the thyroid (84.6 %). In the TE group, there were no recurrences in all patients. There were no significant differences between the groups after exclusion of recurrence in the contralateral thyroid lobe (RR 2.75; 95 % CI 0.08–8.79; р = 0.08). In the TE group, the number of patients with transient and permanent hypothyroidism in the TE group was significantly higher than in the HE group (р <0.001).Conclusion. Hemithyroidectomy is appropriate for the majority of patients with papillary thyroid carcinoma in the absence of extrathyroidal invasion in the neighboring tissues per preoperative examination. For patients after HE, preoperative and postoperative diagnostic examinations are important as most recurrences develop in the contralateral thyroid lobe.
介绍。甲状腺乳头状癌是甲状腺癌最常见的亚型，占病例的95%。通常，这种病理在自身免疫性甲状腺炎(桥本甲状腺炎)的存在下发展，这是各种富碘地区甲状腺功能减退的主要原因。甲状腺乳头状癌预后良好，但也有部分患者会复发，这取决于手术干预的力度。比较自身免疫性甲状腺炎继发甲状腺乳头状癌患者行甲状腺切除术(HE)和甲状腺切除术(TE)后的临床疗效和并发症。材料和方法。回顾性研究纳入2031例甲状腺乳头状癌患者。考虑到个体危险因素，HE组排除67例，TE组排除588例。每组包括688名数据匹配的患者。考虑年龄、性别、原发肿瘤大小、甲状腺外侵、多灶性肿瘤及颈部淋巴结转移等个体因素。在10年的随访中，HE组26例(3.8%)患者诊断复发，TE组11例(1.6%)患者诊断复发。TE术后相对复发风险明显低于HE术后(风险比(RR) 0.41;95%置信区间(CI) 0.21-0.81;r = 0.01)。在HE组中，大多数患者在对侧甲状腺叶复发(84.6%)。TE组患者无复发。排除对侧甲状腺叶复发后，两组间差异无统计学意义(RR 2.75;95% ci 0.08-8.79;= 0.08)。TE组出现短暂性和永久性甲状腺功能减退的人数明显高于HE组(p <0.001)。多数乳头状甲状腺癌患者在术前检查未见邻近组织甲状腺外侵犯的情况下，可行甲状腺切除术。对于HE术后的患者，术前和术后的诊断检查很重要，因为大多数复发发生在对侧甲状腺叶。
