Background: This study compared rates of progression to chronic breast cancer-related lymphedema (defined as a greater than or equal to 10% arm volume change from baseline requiring complex decongestive physiotherapy (CDP) ) following an intervention for subclinical lymphedema (S-BCRL) triggered by bioimpedance spectroscopy (BIS) or by tape measurement (TM). Methods and Results: This stratified, randomized, international trial enrolled new breast cancer patients undergoing: mastectomy/partial mastectomy, axillary treatment (dissection, sentinel lymph node biopsy >6 nodes or radiation), radiation therapy (chest wall/ breast, supraclavicular fossa), or taxane-based chemotherapy. Following post-surgery eligibility reassessment, centralized, 1:1 randomization to prospective surveillance by BIS or TM occurred. S-BCRL detection triggered a 4-week, 12-hour per day, compression sleeve and gauntlet intervention. The primary outcome (n=209), rates of post-intervention progression to CDP, were assessed over three years. Between June 24, 2014 and September 11, 2018, 1,200 patients were enrolled, 963 randomized (BIS n=482;TM n=481) and 879 analyzed (BIS n=442;TM n=437). Median follow-up was 32.9 months (IQR=22,35). BIS patients triggered an intervention at a lower rate than TM patients (20.1%, n=89 vs 27.5%, n=120, p = 0.011). Median months to trigger was longer with BIS than TM (9.7; 95%CI,8.2-12.6 vs 3.9; 95%CI,2.8-4.5, p = 0.001). Overall, 14.4%(n=30) progressed post-intervention, with reduced likelihood for BIS patients than TM patients (7.9%, n=7 vs 19.2%, n=23; RR=0.41; 95%CI,0.13-0.81; absolute reduction 11.3%; 95%CI,2.3%-20.3%; p = 0.016). Conclusions: As compared to TM, BIS provides a more precise identification of patients likely to benefit from an early compression intervention.

Abstract Background: Few studies claimed that dynamic jaw (DJ) mode in Helical TomoTherapy® (HT) could improve the cranio-caudal dose distribution without prolonging the treatment time in treating different types of cancer. Also, studies suggested that DJ with a wider 5 cm field width (FW) could replace fixed jaws (FJ) with 2.5 cm FW to reduce the delivery time with the sustainable plan quality. Yet, the study on breast cancer with supraclavicular fossa (SCF) nodal involvement using DJ mode in HT is limited. This study aims to evaluate the DJ mode retrospectively by comparing their dosimetric quality with normal tissue complication probability (NTCP) of organs at risk and treatment delivery time with FJ mode on treating left-side breast with SCF nodal involvement. Materials and methods: All post-mastectomy patients, who had been irradiated for left-side breast with SCF nodal involvement were selected retrospectively in this study. With the same dose constraint and prescription as the treated DJ2.5 plan, two extra plans using DJ mode with 5 cm FW(DJ5.0) and FJ mode with 2.5 cm FW (FJ2.5) were computed for plan comparison. Results: No statistical significance was found in all the parameters of PTV and OARs, except for V20 of whole lung. DJ5.0 received V20 in ipsilateral left lung than FJ2.5 and DJ2.5. However, the average delivery time of DJ5.0 was significantly lower than that of DJ2.5 and FJ2.5 by almost 40%. Conclusions: No statistical significance was found in those dosimetric and radiobiological parameters among three modes while the delivery time has greatly reduced by using DJ5.0. A shorter treatment time can minimise intra-fractional error and better the patient’s experience during treatment.

Abstract Aim: There are only limited studies available in literature that discuss methods to reduce the oesophageal dose and acute oesophagitis during breast cancer radiotherapy. The aim of this study is to compare dose volumetric parameters of oesophagus in radiation treatment of breast with and without oesophagus delineation. Methods: Treatment plans of 44 patients, who underwent chest wall and supraclavicular fossa irradiation, were selected for the study. Oesophagus was later delineated and treatment replanned using three-dimensional conformal radiotherapy (3DCRT) considering oesophagus as an organ at risk (OAR). The dose prescribed was 40 Gy/15 fractions to the planning target volume (PTV). Dose volumetric parameters of oesophagus such as maximum dose (Dmax), mean dose (Dmean), the percentage of oesophagus volume receiving ≥15Gy (V15), ≥25Gy(V25), ≥33Gy(V33) and ipsilateral lung volume parameters V4, V8 and V16 were compared with already executed plans in which oesophagus was not delineated. Results: Contouring the oesophagus as an OAR as a part of the radiotherapy treatment for Carcinoma Breast resulted in statistically significant reduction in dose to the oesophagus. No statistically significant change was found in the ipsilateral lung volume parameters. No compromise in plan quality was required as evident from the statistically non-significant differences in Homogeneity index and Conformity index. Findings: 3DCRT planning with oesophagus delineation can be considered as a method to reduce oesophageal dose and the acute oesophageal toxicity during radiotherapy for carcinoma breast.

<b><i>Background:</i></b> Malignant cervical lymphadenopathy in the setting of lung cancer represents N3 disease, and neck ultrasound (NUS) with sampling is described in the Royal College of Radiologists ultrasound training curriculum for the non-radiologists. This study reviews the incorporation of NUS +/− biopsy in the routine practice of a lung cancer fast-track clinic in the UK. <b><i>Methods:</i></b> We retrospectively assessed 29 months of activity of a lung cancer fast-track clinic. Systematic focused NUS was conducted in suspected thoracic malignancy, sampling nodes with a ≥5-mm short axis, under real-time US using a linear probe (5–12 Mhz). Fine-needle aspirations (FNAs) with or without 18 Ga core biopsies were taken. <b><i>Results:</i></b> Between August 2017 and December 2019, of 152 peripheral lymph nodes (LNs)/deposits sampled, 98 (64.5%) were supraclavicular fossa LNs with median [IQR] size 12 [8–18] mm. Core biopsies were performed in 54/98 (55%) patients, while all patients had FNAs. No complications occurred. The representative yield was 90/95 (94.7%) in cases with suspected cancer. No difference was seen between FNA versus core biopsy (<i>p</i> = 0.44). Of the 5 non-diagnostic samples, one was FNA only. The commonest diagnosis was lung cancer in 66/98 (67.3%). PDL-1 was sufficient in 35/36 tested (97.2%). ALK-FISH was successful in 24/25 (96%) cases. EGFR mutation analysis was successful in 28/31 (90.3%) cases. Median time from clinic to initial diagnosis was 7 [5–10] days. Computed tomography (CT) scans reported no significant lymphadenopathy in 18/96 (18.7%) cases, yet 10/18 (55.5%) cases were positive for malignancy. <b><i>Conclusion:</i></b> Neck nodal sampling by respiratory physicians was safe, timely, with a high diagnostic yield and suitability for molecular testing. Neck US can provide a timely diagnosis in cases that may be missed by CT alone.

AbstractSolitary fibrous tumor (SFT) is an unusual spindle cell neoplasm that commonly arises from pleura. In the last decade, multiple case reports have described its diverse occurrence in extrapleural locations involving almost every anatomic site. Intravascular SFT is extremely rare and has been reported in inferior vena cava and renal vein only, to the best of our knowledge. SFT of the internal jugular vein has never been reported. We present a case of a SFT arising from internal jugular vein with extraluminal exophytic component extending into supraclavicular fossa. It should also be considered as a differential diagnosis for neoplasm arising from the internal jugular vein.

Objective: The objective of this study was to retrospectively review clinical data, management protocols, and clinical outcomes of patients with fibromatoses of head and neck region treated at our tertiary care center. Methods: We retrospectively reviewed the medical records of 11 patients with confirmed histopathological diagnosis of fibromatosis registered in the Department of Head and Neck Surgery at Tata Memorial Centre, India, between 2009 and 2019. Various clinical and pathological features and treatment modalities were evaluated. Results: Age at diagnosis ranged between 18 and 74 years, with a median age of 36 years. The female-to-male ratio was 5:6. Supraclavicular fossa (n=4) was the most common subsite of origin in the neck (n=8). The lateral (n=2) and posterior cervical regions (n=2) were other common neck subsites. Less commonly involved sites were the mandible (n=1), maxilla (n=1), and thyroid (n=1). A total of eight patients underwent surgery at other centers before being referred to us for further management. Out of a total 11 patients, nine patients had unresectable disease at presentation. Six of the patients with unresectable disease received a combination of weekly doses of vinblastine 6 mg/m2 and methotrexate 30 mg/m2 for a median duration of 6 months (range 6–18 months) followed by hormonal therapy with tamoxifen. Three patients received metronomic chemotherapy followed by hormonal therapy. One treatment-naive patient with fibromatosis of posterior cervical (suboccipital) region underwent R2 resection (excision of bulk of the tumor with preservation of critical structures) at our center along with adjuvant radiotherapy. One pregnant patient reported to us after undergoing surgery outside and defaulting radiotherapy. During median follow-up of 29 months (range 1–77 months), six patients had stable disease, and four patients had disease reduction. Disease progression was seen in one patient. The two-year progression-free survival (PFS) was 90% (95% CI 70%–100%). Conclusion: Gross residual resection (R2) was the mainstay of surgical treatment in our series, as obtaining clear surgical margins is seldom possible in these locally aggressive tumors. Radiotherapy, chemotherapy, and hormonal therapy are the other preferred and more conservative treatment modalities. The goal of surgery should be preserving function with minimal or no morbidity. As fibromatoses in the head and neck region are extremely rare, their treatment awaits the development of standard treatment protocols.
