Unstable isotopes and their capacity to emit ionizing radiation have been employed in clinical practice not only for diagnostic, but also for therapeutic purposes, with significant contribution in several fields of medicine and primarily in the management of oncologic patients. Their efficacy is associated with their ability to provide the targeted delivery of ionizing radiation for a determined duration. These compounds can be used for curative or palliative treatment, as well as for a diagnostic-therapeutic (theranostic) approach. This review summarises the most recent trends in radionuclide treatment for several malignancies, including prostate cancer, neuroendocrine tumours, and hematological and thyroid malignancies, in which radionuclide-based therapies have been employed with high effectiveness.

Abstract Pleomorphic sarcomas or spindle cell sarcomas of the bone are rare malignant tumors that affect the adult. Fracture in the affected bone is the most frequent first symptom. Multimodal treatment is similar to the one for osteosarcoma, but the benefit is less evidence-based, due to the rarity of this sarcoma subtype. The present paper is a case report of a 73-year-old patient, who presented with a comminuted fracture of the distal third of the femur after a fall on ice. Differential diagnosis of bone metastasis was made. After the histopathological confirmation, the surgical team decided to amputate, with prior patient consent. The tumor was staged pT1NxMx, R0. Immunohistochemical studies confirmed the histopathological diagnosis. A lytic lesion in the stump bone appeared on post-operative MRI and was interpreted as skip metastasis. No other metastatic sites were detected. The multidisciplinary team decided for adjuvant chemotherapy (3 courses) and then radiotherapy. He was unable to receive the total planned dose of radiotherapy due to local toxicity. Even so, he is free of recurrence on long-term follow-up.

Abstract Myxofibrosarcoma or myxoid malignant fibrous histiocytoma is one of the most common sarcomas of the limb. It is usually treated multimodally. Most frequent sites of metastasis are the bone, lung and lymph nodes. The present paper is a case report of a 65-year-old male with myxofibrosarcoma of the fibularis longus muscle, for which he first underwent surgery - tumor resection with appropriate margins. The tumor was staged pT2b cN0 cM0. Postoperative PET-CT revealed metabolically inactive pulmonary nodules. Two months after surgery, he underwent adjuvant radiotherapy, a total dose of 60 Gy and 6 courses of chemotherapy (doxorubicin and ifosfamide). Pulmonary nodules have been stationary on all subsequent imagistic studies. He is free of recurrence on long-term follow-up.

Although gastric metastases have been estimated to occur in less than 2% of cancer patients, an increased use of upper digestive tract endoscopy allows for a higher detection of secondary gastric tumors. We describe the case of a 66-year-old male patient presenting with mild pain in the sternum and upper abdominal area. Physical examination revealed a right parietal skull tumor, with no other significant clinical changes. Upon exclusion of an acute coronary syndrome, upper digestive tract endoscopy was performed, showing the presence of an ulcerated tumor located in the gastric fundus. Histopathologic examination of the biopsy sample and immunohistochemical tests suggested a pulmonary origin of the gastric tumor. Whole body computer tomography showed the presence of tumors in the gastric fundus, left lung, liver, kidneys, bones and brain. Transbronchial biopsy of the lung tumor certified the diagnosis of non-small cell lung cancer, with the same immunohistochemical profile as the gastric tumor. Hence, it was considered the origin of the metastases. Biopsy of the skull tumor also had the identical tumor histology. Whole brain radiotherapy was performed for the brain metastases and subsequent chemotherapy was administered. Although non-specific, gastrointestinal signs and symptoms occurring in lung cancer patients should alert the clinicians as to the possibility of gastrointestinal metastases and prompt endoscopic evaluation.

There is ongoing debate regarding the role of neck dissection in differentiated thyroid cancer, about its usefulness in elective settings, and the increased costs regarding morbidity and operative time. This retrospective study aimed to determine the rate of metastases in cervical lymph nodes, to examine the morbidity of this surgery, and to assess whether a pattern of distribution of tumor cells concerning neck lymphatic compartments exists. The most frequent type of cancer to metastasize was papillary cancer, the majority of patients were young with a median of 30 years, predominantly females. Differentiated thyroid cancer frequently metastasizes to the central and lateral compartments of the neck. The morbidity is minimal in a high-volume center. Radical neck dissection is safe and feasible in selected patients with confirmed invaded or enlarged lymph nodes due to differentiated thyroid cancer, and postoperative complications are minimal if the anatomy is correctly identified and the cases strictly

The incidence of thyroid cancer is significantly different between male and female patients. Thyroid cancer is also the only form of cancer where age can be considered a staging variable. Identifying biological prognostic factors such as age or sex is important as it helps select an optimal personalized therapy. The present analysis is an observational, prospective study that enrolled all patients with thyroid disease who were operated upon at a single center. The study aimed to determine the most frequent age at presentation, the predominance of one sex over the other, the incidence of malignant thyroid disease, and the relative risk for each sex to develop thyroid carcinoma. The incidence of thyroid carcinoma was higher for women than for men, with a higher relative risk in the female subgroup. Incidence was also highest in the 50-60-year-old group. Given that studies show better survival for women and for younger patients, even when presenting with advanced disease, compared with older, male patients, such prognostic indicators should be a factor in the treatment decision.

Microsatellite instability (MSI) is a feature of colorectal tumors that develops as a result of inactivation of the DNA mismatch repair system. It is found in about 15% of all colorectal cancers and is an important prognostic molecular marker when assessing patients with colorectal cancer. It can influence prognosis and treatment decisions in both the advanced and early stages. Although in early stages this marker suggests a favorable prognosis and presents an important argument against adjuvant treatment in stage II disease, in metastatic stages it no longer associated with such an optimistic outcome. The present trial is a prospective, single-center study which included 122 colorectal cancer patients who were tested for MSI using immunohistochemistry. The trial included patients with stage II to IV colorectal cancer, treated in the Prof. Dr. Agrippa Ionescu Emergency Hospital, Bucharest, Romania. Follow-up data were collected during a 24-month period. The study attempted to determine whether differences exist in overall survival for MSI (microsatellite instability) vs. MSS (microsatellite stable) colorectal cancer and to ascertain whether sex of the patient influences prognosis in MSI patients, irrespective of stage or treatment. Results demonstrated no significant differences in survival for MSI vs MSS colorectal patients, and patients’ gender proved not to influence the outcome in MSI patients.

Objective. The purpose of this paper is to review the current concepts in the literature regarding the beneficial effects of adjuvant surgery after concurrent radio-chemotherapy for locally advanced cervical cancer. Method. Research of the literature was performed using PubMed databases in order to find articles relevant to the central topic. The PICOS criteria were used to filter the results. The paper was then structured according to the PRISMA guideline. Results. 50 individual papers were analyzed and sorted according to their relevance for the topic. 18 were classified as relevant. There was little agreement as to how beneficial adjuvant hysterectomy is in locally advanced cervical cancer after chemoradiotherapy. Some articles concluded that patients with a total clinical response after initial treatment might have superior progression-free survival and overall survival after surgery. 2 articles underlined the importance of accurate restaging after primary treatment. The lack of benefit for surgery in patients with bulky disease or persistent adenopathies was agreed upon in all cases. Conclusions. The decision for adjuvant hysterectomy with or without lymphadenectomy is a controversial one and has to be personalized and taken in a multidisciplinary team.

Basal Cell Carcinoma is the most common human malignant neoplasm. Vulvar basal cell carcinoma is rare, accounting for less than 5% of all vulvar neoplasms. Vulvar basal cell carcinomas are usually diagnosed late because they are often asymptomatic and tend to grow at slow rates. They are usually diagnosed late because they are often asymptomatic. However, these tumours may appear in areas which are normally covered with ultraviolet light. We present the case of a 60 years old woman diagnosed with invasive breast cancer for which she underwent surgery followed by chemotherapy and radiotherapy. The patient presented to our department with an ulcerated vulvar lesion. On inspection, the tumour measured 3/2 cm and was located on the left labium majus. The biopsy confirmed the diagnosis of vulvar basal cell carcinoma and a wide local excision was performed with no relapse at one year. In conclusion, early detection of BCC’s is critical to allow complete surgical cure so any abnormality on the vulva should be biopsied. A wide safety margin of 1cm should be achieved when resecting the tumour and the physician should keep in mind that the BCC’s of the vulva has a high recurrence rate. Previous chemotherapy is not associated with this type of non-melanoma skin cancer.
