BACKGROUND: The median time to recurrence of glioblastoma (GB) following multimodal treatment is ∼7 mo. Nearly all cancers recur locally, suggesting that augmenting local treatments may improve outcomes. OBJECTIVE: To investigate whether intraoperative radiotherapy (IORT) to the resection cavity is safe and effective. METHODS: INTRAGO was a phase I/II trial to evaluate the safety and tolerability of IORT with 20 to 40 Gy of low-energy photons in addition to standard radiochemotherapy (ClinicalTrials...

BACKGROUND: Breast reconstruction with a Becker-type expander is a common technique following mastectomy. However, inconsistency remains in the literature regarding risk factors for the survival of a Becker-type expander following immediate breast reconstruction. This study's purpose is to investigate possible risk factors for the Becker-type expander survival and to evaluate the complications related to expander removal following immediate breast reconstruction. METHODS: We performed a retrospective chart review of consecutive women who underwent a mastectomy followed by immediate breast reconstruction with a Becker-type expander from November 2010 to November 2016...

OBJECTIVE: Intraoperative radiotherapy (IORT) after surgical resection using a low-kV-X-ray source is a proven method used in cancer treatment. However, the shape and size of the targeted surface area are limited to the size of the available applicators. This can lead to nonconformal and therefore suboptimal treatment for many patients. METHODS: A system is proposed comprising an X-ray source with an applicator for surface irradiation mounted on a robotic arm. This is controlled by an algorithm designed for planning the required continuous path, enabling irradiation of any desired shape with a controlled dose distribution...

We present a rare case of supratentorial meningeal melanoma associated with ipsilateral nevus of Ota, and a review of the literature. The patient was a 32-year-old man with a right-sided nevus of Ota, presenting with unconsciousness. His CT and MRI scans revealed an extra axial tumor with dural tail signs; no lesion was detected on systemic examination. Intraoperatively, the tumor demonstrated black hyperpigmentation and was histologically diagnosed as malignant melanoma. Following surgery, he received radiotherapy and chemotherapy...

Intraoperative radiotherapy (IORT) for breast cancer has challenged the standard external beam radiotherapy (EBRT) and has been shown to be non-inferior for treating early breast cancer in the past decade. Several technologies have been tested for IORT and various randomised controlled trials are still ongoing. Different methods of application of IORT have also been evaluated, from early breast cancer to tumour bed boost radiotherapy amongst high risk women. TARGIT-A and ELIOT trials have reported a low incidence of local recurrence and good survival in both arms...

Synchronous multiple primary lung cancer (SMPLC) means tumours present at the same time, which are separate and have different histology. We present the case of a 66-year-old patient with a combination of small-cell lung carcinoma (SCLC) with adenocarcinoma in the same lobe with metastasis of SCLC in the mediastinal lymph node. This is a rare case. We performed a standard left upper video-assisted thoracoscopic lobectomy with mediastinal lymphadenectomy and adjuvant therapy targeted to SCLC was administered...

A breast cancer with tumors smaller than or equal to 5mm in diameter is treated as a microscopic lesion and axially lymph node metastasis is considered to be rare. A 52-year-old female was found to have an abnormal shadow on mammography. An ultrasonography revealed a poorly defined and irregular shaped mass with calcification, 4mm in diameter, in the AC area of her left breast. We performed vacuum-assisted biopsy and diagnosed with invasive ductal carcinoma. Under a preoperative diagnosis of left breast cancer with cT1aN0M0, stage I , Luminal A like, we underwent partial mastectomy with sentinel lymph node biopsy...

The TARGIT-A (TARGeted Intraoperative radioTherapy) multicentre study of early breast cancer compared intraoperative radiotherapy with external radiotherapy. While the intraoperative radiotherapy was standardised, the external postoperative comparison treatment followed established routines in the participating treatment centres resulting in substantial variations in dosages and treatment durations. The uncertainties in the interpretation of the study results created by the design of the TARGIT-A study constitute substantial obstacles to the possible introduction of intraoperative radiotherapy for early breast cancer...

Malignant mesothelioma of the tunica vaginalis testis (MMTVT) is an extremely rare tumour, usually mimicking benign pathologies of the scrotum. Our case is an 84-year-old male patient who appealed with a painless, left-sided scrotal swelling longer than 2 months. Although the level of tumour markers was normal, ultrasonographic examination results forced us to perform an inguinal scrotal exploration. Multiple small papillary tumours, both on tunica vaginalis and tunica albuginea, were detected intraoperatively...

PURPOSE: Recently, prostate-specific membrane antigen-radioguided surgery (PSMA-RGS) has been introduced as a promising new and individual treatment concept in patients with localised recurrent prostate cancer (PC). In the following, we want to review our experience with PSMA-RGS in patients with localised biochemical recurrent PC. METHODS: A non-systematic review of the literature was carried out with focus on technical and logistical aspects of PSMA-RGS. Furthermore, published data on intraoperative detection of metastatic lesions compared to preoperative PSMA-PET and postoperative histopathology, postoperative complications as well as oncological follow-up data are summarized...

BACKGROUND: The incidence of cancer in transplant recipients is higher than in the general population. Cutaneous and lymphoproliferative tumors are the primary neoplasms that will develop these patients. Little is known about the transmission of cancer in organ and tissue donation; it has been described that neoplasms can be transmitted to immunosuppressed patients when donor organs with neoplasms are inadvertently transplanted. CASE REPORT: Patient of 29 years of age who underwent kidney transplantation 10 years ago...

The spread of systematic screening and the emergence of oncoplastic techniques allow more breast conservative treatment associating lumpectomy and external beam radiation therapy. In order to furthermore facilitate the patient's treatment, intraoperative radiation therapy (IORT) has been developed. The oncological safety of this technique has been studied, and is considered acceptable. Many questions remain unsolved in regard of the toxicity of this procedure as well as the patient's selection criteria. In this study, we present the first results and complications rate of patients treated by IORT in a single French institution...
