Solitary Fibrous Tumor in the Round Ligament of the Liver: A Fortunate Intraoperative Discovery

Solitary fibrous tumors (SFTs) are mesenchymal neoplasms of fibroblastic origin, most commonly found in the pleura. Numerous extrathoracic locations have been reported during the last 2 decades. Herein, we report the first case of an SFT in the round ligament of the liver. A 46-year-old Caucasian man presented with a 12-month history of abdominal pain. An ultrasonography-guided microbiopsy first revealed a desmoid tumor. After failure of first- and second-line medical treatments (celecoxib and tamoxifen, then imatinib), histological reexamination was suspicious for a low-grade sarcoma. MRI was also suspicious for a malignant process. Hence, surgery was decided. Laparotomy found a huge and well-limited tumor that, unexpectedly, was appended to the round ligament of the liver and free from any other intra-abdominal contact. The tumor was easily removed. Excision was monobloc and macroscopically complete. Histological analysis diagnosed an SFT arising from the round ligament of the liver. No adjuvant treatment was given. Ten months after surgery, the patient is alive without any signs or symptoms of relapse. This is the first report of SFT arising from the round ligament of the liver. It illustrates the difficulty in diagnosing such tumors. Whilst diagnosis of SFT is rare, it should be kept in mind to allow early diagnosis and complete surgical resection, which provide the best chance for recovery

Primary leiomyosarcoma of the seminal vesicle: Case report and review of the literature

International audienceAbstract Background Primary leiomyosarcoma of the seminal vesicle is exceedingly rare. Case Presentation We report a case of a 59-year-old man with tumour detected by rectal symptoms and ultrasonography. Computed tomography and magnetic resonance imaging suggested an origin in the right seminal vesicle. Transperineal biopsy of the tumour revealed leiomyosarcoma. A radical vesiculo-prostactectomy with bilateral pelvic lymphadenectomy was performed. Pathological examination showed a grade 2 leiomyosarcoma of the seminal vesicle. The patient received adjuvant radiotherapy. He developed distant metastases 29 months after diagnosis, and received chemotherapy. Metastatic disease was controlled by second-line gemcitabine-docetaxel combination. Fifty-one months after diagnosis of the primary tumour, and 22 months after the first metastases, the patient is alive with excellent performance status, and multiple asymptomatic stable lung and liver lesions. Conclusions We report the eighth case of primary leiomyosarcoma of the seminal vesicle and the first one with a so long follow-up

Impact of radiotherapy in the management of locally advanced extrahepatic cholangiocarcinoma

BACKGROUND: Optimal therapy for patients with unresectable locally advanced extrahepatic cholangiocarcinoma (ULAC) remains controversial. We analysed the role of radiotherapy in the management of such tumors. METHODS: We retrospectively reviewed the charts of patients treated in our institution with conformal-3D external-beam-radiotherapy (EBRT) with or without concurrent chemotherapy. RESULTS: Thirty patients were included: 24 with a primary tumor (group 1) and 6 with a local relapse (group 2). Toxicity was low. Among 25 patients assessable for EBRT response, we observed 9 complete responses, 4 partial responses, 10 stabilisations, and 2 progressions. The median follow-up was 12 months. Twenty out of 30 patients (66%) experienced a relapse, which was metastatic in 75% of cases in the whole series, 87% in group 1, 60% in group 2 (p = 0.25). Twenty-eight patients (93%) died of relapse or disease complications. Median overall survivals in the whole group and in group 1 or 2 were respectively 12, 11 and 21 months (p = 0.11). The 1-year and 3-year progression-free survivals were respectively 38% and 16% in the whole series; 31% and 11% in group 1, 67% and 33% in group 2 (p = 0.35). CONCLUSION: EBRT seems efficient to treat ULAC, with acceptable toxicity. For primary disease, the high rate of metastatic relapse suggests to limit EBRT to non-progressive patients after induction chemotherapy

Efficacy of epidermal growth factor receptor targeting in advanced chordoma: case report and literature review

<p>Abstract</p> <p>Background</p> <p>Chordomas are very rare low-grade malignant bone tumors that arise from the embryonic rests of the notochord.

Impact of the Siewert Classification on the Outcome of Patients Treated by Preoperative Chemoradiotherapy for a Nonmetastatic Adenocarcinoma of the Oesophagogastric Junction

The aim of the study is to analyze the impact of the Siewert classification on the pathological complete response (pcR), pattern of failure, and general outcome of patients treated, by preoperative chemoradiotherapy and surgery for an gastroesophageal junction adenocarcinoma (OGJA). From 2000 to 2008, the charts of 68 patients were retrospectively reviewed. Tumor staging reported was UST1/T2/T3/T4/unknown, respectively, n = 1/7/54/5/1 patients, and N0/N1/unknown, respectively, n = 9/58/1 patients. Patients received primary external-beam radiotherapy with concurrent chemotherapy followed by surgical resection (Siewert I: upper oesogastrectomy; Siewert II/III: total gastrectomy with lower oesophagectomy). Overall survival (OS), overall relapse rate (ORR), cumulative rate of local (CRLR), nodal (CRNR), and metastatic (CRMR) relapse, and their prognostic factors were retrospectively analyzed. Median follow-up was 77.5 months. Median OS was 41.7 ± 5.2 months. The 3-year ORR was 48%. Using univariate analysis ORR was significantly increased for patients with Siewert II/III compared to Siewert I tumors (27.3% versus 62%, p=0.047). Siewert I tumors had also statistically lower CRNR and CRMR compared to Siewert II/III tumors (0/9.1% versus 41.3/60.2% resp., p=0.012), despite an equivalent cumulative rate of local relapse and pathological complete response rate between the three groups. For OGJA treated with preoperative CRT and surgery, ORR and CRMR were lower for patients with Siewert I tumors in comparison with Siewert II/III tumors

Metastatic Intimal Sarcoma of the Pulmonary Artery Sensitive to Carboplatin-Vinorelbine Chemotherapy: Case Report and Literature Review

Pulmonary artery intimal sarcoma (PAIS) is a very rare tumour with a very poor prognosis. In advanced stages, chemotherapy and radiotherapy are poorly efficient, and no standard chemotherapy guideline is currently available. Here, we report on a 37-year-old woman with PAIS initially treated with surgical resection who developed metastatic relapse refractory to anthracycline-based chemotherapy, then trabectedin, then pazopanib. The patient was then given carboplatin-vinorelbine chemotherapy. The treatment was well tolerated, and, rapidly, a CT scan showed an objective response that lasted 8 months despite the 4th therapeutic line. We review the literature and show that our case is the second one that provides evidence of the efficacy of platinum-vinorelbine regimens in this aggressive tumour.

Gastrointestinal Stromal Tumour with Synchronous Bone Metastases: A Case Report and Literature Review

Gastrointestinal stromal tumours (GISTs) are mesenchymal tumours of the digestive tract, derived from Cajal interstitial cells. Bone metastases are very rare, and there is no consensus regarding their treatment. Here, we present the unusual case of a 66-year-old man with a gastric GIST with synchronous bone and liver metastases, fully documented at the pathological and molecular levels with a KIT exon 11 mutation. After 9 months of imatinib, the scanner showed a 33% partial response of target lesions. We also review the literature and describe the characteristics, treatment, and outcome of all cases previously reported
