Quantification of Dosimetry Improvement With or Without Patient Surface Guidance

PurposeNon-coplanar beams and arcs are routinely used to improve dosimetry for intracranial cases but their application for extra-cranial cases has been hampered by the risk of collision. This has led to conservative beam selection whose impact on plan dosimetry has not been previously studied. Methods and materialA full-body 3D patient surface was acquired using optical cameras for a single lung patient at the time of CT simulation. Eight SBRT plans were created for the patient, with varying degrees of non-coplanarity and deliverability. The plans included VMAT and IMRT plans ranging from simple, coplanar arcs to multiple non-coplanar arcs and IMRT beams. There was a total of 70 fields created across the 8 plans, of which 21 fields were undeliverable with a 5cm buffer. OAR metrics including R50, Dmax 2 cm from the PTV, lung V20 and chest wall V30 were evaluated. Five expert SBRT dosimetrists from five institutions evaluated field deliverability, with or without the guidance of the clearance map. ResultsIn the dosimetry evaluation, a clear trend in increasing dosimetric compactness and OAR sparing is observed with increasing plan non-coplanarity. R50, Dmax 2cm, lung V20, and chest wall V30 decreased 41%, 39%, 43%, 57%, respectively, from plan 1 (two coplanar partial arcs) to plan 8 (19 non-coplanar IMRT beams). In the observer tests, the expert dosimetrists’ ability to accurately discern beam deliverability due to collision significantly increases with the clearance map. The errors in predicting colliding fields were eliminated using the whole-body surface and clearance map, and the user was able to select fields based on plan quality and patient comfort instead of being overly conservative. ConclusionThe study shows that incorporating a personalized, whole-body clearance map in the treatment planning workflow can facilitate the adoption of non-coplanar beams or arcs that benefit the SBRT plan dosimetry.

Understanding Public Perceptions of Nipple and Scar Characteristics After Chest Wall Masculinization Surgery.

Surgical chest masculinization procedures, especially gender-affirming top surgery (GATS), are becoming increasingly prevalent in the USA. While a variety of surgical techniques have been established as both safe and effective, there is limited research examining ideal aesthetic nipple appearance and incision scar pattern. This study employs patient images to understand the public's perception on top surgery outcomes when adjusting for BMI ranges and Fitzpatrick skin types. Images from RealSelf modified via Adobe Photoshop depicted various scar types and nipple-areolar complex (NAC) sizes/positions. A Qualtrics survey was distributed utilizing Amazon Mechanical Turk. Statistical analysis was performed through JMP Pro 17 for ordinal and categorical values, with a p value less than or equal to 0.05 statistically significant. A moderately sized and laterally placed NAC was preferred. A transverse scar that resembles the pectoral border between the level of the inframammary fold and pectoral insertion was deemed most masculine and aesthetic. Majority of results demonstrated that this is unaffected by Fitzpatrick skin types. Increased BMI images impacted public preferences, as a nipple placed farther from the transverse incision (p=0.04) and a transverse scar position closer to the IMF was preferred in higher BMI patients. An understanding of the most popular NAC and scar choices, as well as how these factors may differ when considering a Fitzpatrick skin type or BMI categorization was attained. This validates the importance of patient-centered approach when employing surgical techniques in GATS. Future studies intend to obtain reports from actual patients considering GATS. This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

Primary skeletal muscle anaplastic large cell lymphoma mimicking dermohypodermatitis

Anaplastic large cell lymphoma (ALCL) is a non-Hodgkin’s lymphoma (NHL) characterized by a strong expression of CD30. ALK-ALCL is a rare subtype that typically affects older adults and has a poor prognosis. It rarely arises in the skeletal muscle, particularly with primary involvement. Herein, we report the case of ALK-ALCL with primary involvement of the muscle. A 69-year-old male patient presented with fever, an erysipeloid placard in the axillary cavity, and the lateral and anterior chest wall initially treated with antibiotic therapy without improvement. A CT scan revealed a tumor proliferation in the pectoralis minor muscle, whose anatomopathological and immunohistochemical studies were in favor of ALCL. ALCL may mimic common dermatological conditions, including dermohypodermatitis. Therefore, in cases where symptoms do not resolve after conventional treatment, radiological examinations or even a biopsy should be considered to determine the cause of the symptoms and to initiate an appropriate treatment strategy. Key words: Anaplastic large cell lymphoma, Dermohypodermatitis, Muscle

Adjuvant and Neoadjuvant Therapy for Breast Cancer: A Systematic Review.

Breast cancer (BC) is the most frequent type of cancer among women. The neoadjuvant therapy was administered before surgery, and the adjuvant therapy was administered post-surgery. The goal of this systematic review is to study the effects of adjuvant and neoadjuvant BC therapy on patient outcomes and mortality. In July 2023, systematic searches were conducted through the Cochrane Library, Web of Sciences, Google Scholar, EMBASE, and PubMed databases. The search method focused on studies that included all patients with BC stages 1, 2, and 3 and excluded studies that included patients with metastatic and recurrent BC. The risk of bias in the included studies was evaluated using the Cochrane risk of bias technique. Throughout our search, 27 relevant studies with 161,552 patients were discovered. Anti-human epidermal growth factor 2 therapy (trastuzumab, pertuzumab), chemotherapy (anthracycline), endocrine therapy (tamoxifen, aromatase inhibitor), and bisphosphonates were recommended treatments for BC patients. Choices for radiotherapy included whole breast, partial breast, tumor bed boost, regional nodes, and chest wall choices after breast-conserving surgery. We discover that while the majority of treatments reduced the mortality or recurrence rates of BC, anthracycline, chemotherapy, and radiation led to an overall rise in non-BC deaths. The systemic assessment discovered several variables that impact a patient's quality of life. Based on these advantages and disadvantages, various treatment options for patients and recommendations for groups of women are made.

The role of 3D printing in chest wall reconstruction.

Technology is advancing fast, and chest wall surgery finds particular benefit in the broader availability of three-dimensional (3D) reconstruction and printing. An increasing number of reports are being published on the use of these resources in virtual 3D reconstructions of chest walls in computed tomography (CT) scans, virtual surgeries, 3D printing of real-size models for surgical planning, practice, and education, and of note, the manufacture of customized 3D printed implants, changing the fundamental conception from a surgery that fits all, to a surgery for each patient. In this review, we explore the evidence published on simple chest wall reconstruction, including the use of 3D technology to assist in the improvement of the repair of the most frequent chest wall deformities: pectus excavatum and carinatum. Current studies are oriented to the automatization and customization of transthoracic implants, as well as education on real-size models. Next, we investigate the implementation of 3D printing in the repair of complex chest wall reconstruction, comprised of infrequent chest wall deformities such as pectus arcuatum and Poland syndrome. These malformations are very heterogeneous resulting in a high degree of improvisation during the surgical repair. In this setting, 3D technology plays a role in the standardization of a process that contemplates customization, concepts that may seem contradictory. Finally, 3D printing with biocompatible materials is rapidly becoming the first choice for the reconstruction of wide chest wall oncological resections. In this work, we review the first and most important current publications on the subject.

Primary Malignant Melanoma of the Cervix with Rapidly Progressing Metastases

Introduction: Mucosal melanomas only account for 0.03% of newly diagnosed cancer cases. Female genital tract melanomas account for only 3% of all melanomas, with melanoma of the cervix accounting for less than 3% of all female genital tract melanomas. It is difficult to understand how mucosal melanomas arise as the pathogenesis is still unknown. The incidence of cutaneous melanoma has greatly increased over the years whereas the incidence of mucosal melanomas has stayed relatively steady. Given the rarity of melanoma of the cervix, a standard of care treatment has not been established. Based on the limited cases that have previously been treated, the first option is surgery for early stage melanomas with adjuvant radiation therapy indicated in some cases. The use of systemic chemotherapy is still controversial as it has not been shown to prevent metastases. Case Report: A 66-year-old postmenopausal female presented with heavy vaginal bleeding. A transvaginal ultrasound showed a complex cystic structure in the cervix and she was referred to gynecologic oncology. She was up to date on her pap smears, and they have always been normal. Patient was found to have a fungating 4 x 5 cm mass in the upper vagina and pathology demonstrated poorly differentiated malignant neoplasm. The patient was diagnosed with FIGO Stage IIA2 cervical cancer. Patient’s initial PET/CT demonstrated hypermetabolic area in the cervix consistent with known cervical carcinoma with no other uptake in the uterus. Weekly chemosensitization with cisplatin and external beam radiation was initiated. On clinical examination after treatment by the gynecologic oncologist, visible disease was seen confined to the cervix. An MRI of the pelvis showed response with the suspected tumor limited to the cervical stroma in the anterior and lateral portion of the cervix with no definitive parametrial tumor and no evidence of nodal metastasis. Second opinion from pathology review was received and results showed poorly differentiated malignant neoplasm immunohistochemically consistent with “melanoma”. After 25 fractions of daily radiotherapy with weekly cisplatin, patient underwent exploratory laparotomy for radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymph node sampling. Final pathology of the uterus and cervix showed invasive poorly differentiated melanoma with deepest invasion of melanoma measuring 8mm and negative surgical margins. All lymph nodes removed during surgery were negative for malignancy. Adjuvant Pembrolizumab was started at this time. Two months postoperatively, the patient underwent CT surveillance again due to new onset chest wall and axillary nodules varying in size from 2-4 cm. Right chest wall axilla biopsy pathology was consistent with melanoma. At this time Pembrolizumab was discontinued and the patient was transitioned to Nivolumab and Ipilimumab 19 days after discontinuing Pembrolizumab. Four months postoperatively, additional CT scans were performed showing widespread metastatic disease in the lungs, chest wall, liver, peritoneum, retroperitoneum and left eye. Patient underwent left frontal craniotomy with tumor resection, and pathology was consistent with metastatic melanoma. Subsequent to craniotomy, the patient underwent three treatments with stereotactic radiosurgery. Despite treatment, six months postoperatively, the patient’s symptoms continued to progress with slurred speech, generalized weakness and abdominal pain. Ultimately, the patient passed away nine months after the diagnosis and four months after a combination of external beam radiotherapy, surgery, and vaginal brachytherapy. Discussion: Melanoma of the cervix is a rare type of cervical cancer with poor prognosis. Globally, 5-year survival is 18.8% for stage I, 11.1% for stage II, and 0% for stages III–IV. It has been shown that median overall survival time decreases with increasing FIGO stage. Risk factors have not been identified for gynecologic melanomas or most other mucosal melanomas. Pembrolizumab is most effective for cutaneous melanomas, however, has been shown to prolong progression free survival in mucosal melanomas. The median overall survival is significantly shorter for patients with mucosal melanoma (11.3 months) as compared to patients with a cutaneous primary (23.5 months). Primary malignant melanoma of the cervix (PMMC) remains a rare tumor and the prognosis is generally poor. Radical hysterectomy, chemoradiation, and immunotherapy have all been utilized in the treatment of PMMC. Further investigation of primary melanoma of the cervix is necessary to formulate a standard of care treatment.

The Impact of Preoperative Combined Pectoserratus and/or Interpectoral Plane (Pectoralis Type II) Blocks on Opioid Consumption, Pain, and Overall Benefit of Analgesia in Patients Undergoing Minimally Invasive Cardiac Surgery: A Prospective, Randomized, Controlled, and Triple-blinded Trial

ObjectiveAcute postoperative pain remains a major obstacle in minimally invasive cardiac surgery (MICS). Evidence of the analgesic benefit of chest wall blocks is limited. This study aimed to assess the influence of combined pectoserratus-plane-block plus interpectoral-plane-block (PSPB+IPPB) on postoperative pain and overall benefit of analgesia compared to placebo. DesignProspective, randomized, triple-blinded. SettingThe operating room, intensive care unit of a university hospital Participants60 patients undergoing elective right-lateral MICS. InterventionsPatients were randomly assigned to preoperative PSPB+IPPB with 30 ml ropivacaine 0.5% or saline. Measurements and Main resultsThe primary endpoint was total intravenous morphine milligram equivalents administered in the first 24 hours after extubation (24 h - ivMME). Secondary endpoints included the Overall Benefit of Analgesia Score (OBAS) at 24h after extubation and repeated visual analogue scale (VAS). 24 hours - ivMMEs were significantly lower (median (IQR): 4.2 mg (2.1 – 7.9) versus 8.3 mg (4.2 - 15.7); p = 0.025; mean difference: 6.7 mg (0.94-12 mg), p = 0.024; Cohen's d: 0.64 (0.09-1.2)). Moreover, OBAS at 24 hours and VAS after extubation were significantly lower (4.0 (3.0 – 6.0) versus 7.0 (3.0 – 9.0), p = 0.043; 0.0 cm (0.0 - 2.0) versus 1.5 cm (0.3 - 3.0); p = 0.030). VAS did not differ between groups at later points. ConclusionsPre-operative PSPB+IPPB reduced 24 hours post-extubation opioid consumption, pain at extubation and OBAS. Given its low risk and expedient placement, it could be a helpful addition to MICS protocols. Future studies should evaluate these findings in multicenter settings, and further elucidate the optimal timing of block placement.

Poland syndrome: a case report

Poland syndrome is characterized by the absence or hypoplasia of other chest muscles: small pectoral muscle, anterior tightened muscle, grandorsal muscle, and deltoid muscle. Anomalies of the thoracic cage: agenesis or hypoplasia of one or more costal segments, pectus carinatum, excavatum, clavicular hypoplasia, pulmonary herniation. Abnormalities of the mammary region: agenesis or hypoplasia of the breast, areola and nipple. The reported incidence of Poland’s syndrome ranges from 1 in 7,000 to 1 in 100,000. Males are affected more frequently by a 2:1 to 3:1 ratio Poland’s syndrome has also been diagnosed in 1 of 19,000 mammograms. The right side of the body was found to be involved in 60% to 75% of patients - associated malformations: genitourinary malformations, cardiac malformation, hepatic and biliary tract malformations. Case report Our case involves a 7-month-old boy with no medical history of cardiac or respiratory complaints. This is a male child with around 65cm height, and 7kg weight. There is no family history of consanguineous marriage and no family history of congenital anomalies. All siblings are alive and healthy. The child’s milestones are within normal limits. There is aplasia of the right sternocostal head and clavicular heads and abdominal head of the pectoralis major muscle, there is a hypoplasia of the right nipple and breast and absence of subcutaneous fat on the same side. Ribs are visible on the right chest wall. Physical examination shows no history of hand and digit anomaly and no rib anomalies. Chest wall asymmetry with right chest wall showing depression on axillary floor. The anterior axillary fold is absent. On attempting abduction of the shoulder, it shows the absence of the sternocostal head of the pectoralis major.

Bronchoscopic management of bronchopleural fistula using free fat pad transplant with platelet-rich plasma: a case study

BackgroundA bronchopleural fistula (BPF) occurs when an abnormal connection forms between the bronchial tubes and pleural cavity, often due to surgery, infection, trauma, radiation, or chemotherapy. The outcomes of both surgical and bronchoscopic treatments frequently prove to be unsatisfactory.Case presentationHere, we report a case of successful bronchoscopic free fat pad transplantation combined with platelet-rich plasma, effectively addressing a post-lobectomy BPF. Contrast-enhanced chest tomography revealed pleural thickening with heterogeneous consolidations over the right upper and middle lobes, indicative of destructive lung damage and bronchiectasis. The patient underwent thoracoscopic bilobectomy of the lungs. During surgery, severe adhesions and calcification of the chest wall and lung parenchyma were observed. The entire hilar structure was calcified, presenting challenges for dissection, despite the assistance of energy devices. Bronchoscopic intervention was required, during which two abdominal subcutaneous fat pads were retrieved.ConclusionThis innovative approach offers promise in the management of BPF and signals potential advancements in enhancing treatment efficacy and patient recovery.

Analysis of different outcome parameters and quality of life after different techniques of free vascularized lymph node transfer

ObjectiveVascularized lymph node transfer (VLNT) has become an important surgical technique in the treatment of lymphedema. Considering the different available regions available for flap harvest, we aimed to analyze different donor sites for VLNT with respect to donor site morbidity, impact on limb volume, and patient-reported outcome measurements (PROMs). MethodsA single-center prospective study of all patients undergoing VLNT at the Department of Plastic Surgery and Hand Surgery of the University Hospital Zurich between September 2016 and 2023 was conducted. Lymph nodes were harvested either from the omentum (gastroepiploic [GE]-VLNT), the lateral thoracic wall (LTW), or the superficial inguinal region (SI-VLNT). Volume measurements and PROMs were assessed preoperatively and at different postoperative intervals. ResultsOverall, 70 patients with upper limb lymphedema (21%) or lower limb lymphedema (79%) with different lymphedema stages were included. There were 49 patients who underwent GE-VLNT, followed by LTW-VLNT (n = 16) and SI-VLNT (n = 5). Lymph node harvest from the SI was associated with a significantly higher frequency of seroma development. The average percentage volume loss related in comparison to the preoperative volume of the affected limb was 9% after GE-VLNT, 10% after LTW-VLNT, and 5% after SI-VLNT without a significant difference between the groups. PROMs revealed significant improvements for physical functioning, symptoms and psychological well-being, with no differences between the VLNT techniques. ConclusionsVLNT leads to a significant improvement of quality of life and can decrease limb volume effectively, regardless of the selection of donor site. GE-VLNT has become our flap of choice owing to its low donor site morbidity and its properties that allow a double transplantation while avoiding a second donor site.

Classification of the Volume of Tumor Lesion of the Chest Wall as A Prerequisite for Planning Surgical Treatment

Tumors of the chest wall are a heterogenous group of neoplasms per nosology, clinical progression, and treatment methods. Primary tumors of this location, according to some authors, comprise between 1 and 5 %, and 60 % of them are malignant. Tumors of the chest wall can have not only various nosological forms but also varying volume, location, affect different structures of the chest wall which are determined during physical exam. Despite the progress in drug therapy, radical surgical intervention is a prerequisite for successful treatment of patients with malignant tumors of the chest wall. One of the most important prognostic factors is sufficient margin during chest wall resection. The international tumor classification system Tumor, Nodus and Metastasis (TNM) does not give a complete understanding of the volume of lesions and therefore does not allow to correctly plan resection volume and defect reconstruction based on its data.The article presents a classification of tumor volume of the chest wall proposed by the Sarcoma Research Association which allows to expand indications for surgical treatment and select the optimal type of defect reconstruction.

Correlation of anterior chest wall anomalies and spinal deformities: a comprehensive descriptive study.

To investigate the association and evaluate the characteristics between different types of anterior chest wall and spinal deformities. A total of 548 patients with anterior chest wall deformities were included in this study. Clinical and radiological examinations were performed to determine spinal deformities. The type and severity of the spinal deformities were evaluated and their relationships with chest wall deformity subtypes were statistically analyzed. Spinal deformities were identified in 93 (16.97%) patients. The patients were subdivided into 71 (76.3%) male and 22 (23.7%) female patients. A spinal deformity was detected in 57 (13%) of 418 pectus excavatum (PE) patients, in 23 (19%) of 117 pectus carinatum (PC) patients, and in all patients with mixed pectus deformity (PE + PC), syndromic deformity and rib anomalies. In the PE group, scoliosis, and kyphosis were observed at 57.9 and 31.6%, respectively. In the PC group, these rates were 43.5 and 47.8%, respectively. Idiopathic scoliosis was observed in 42 (77.7%) and constituted the most common scoliosis subgroup. The main thoracic curvature was the most common curve pattern, which was observed in 15 (35.7%) patients with idiopathic scoliosis. Idiopathic scoliosis with main thoracic curvature is the most common deformity in patients with anterior chest wall deformity. Spinal deformities are more common in male patients with chest deformities. Kyphosis is found in a significant number of PE and PC patients. Patients with mixed PE and PC, rib anomalies, and syndromic disease are more likely to have spinal deformities.

EmoWear: Wearable Physiological and Motion Dataset for Emotion Recognition and Context Awareness

The EmoWear dataset provides a bridge to explore Emotion Recognition (ER) via Seismocardiography (SCG), the measurement of small cardio-respiratory induced vibrations on the chest wall through Inertial Measurement Units (IMUs). We recorded Accelerometer (ACC), Gyroscope (GYRO), Electrocardiography (ECG), Blood Volume Pulse (BVP), Respiration (RSP), Electrodermal Activity (EDA), and Skin Temperature (SKT) data from 49 participants who watched validated emotionally stimulating video clips. They self-assessed their emotional valence, arousal, and dominance, as well as extra questions about the video clips. Also, we asked the participants to walk, talk, and drink, so that researchers can detect gait, voice, and swallowing using the same IMU. We demonstrate the effectiveness of emotion stimulation with statistical methods and verify the quality of the collected signals through signal-to-noise ratio and correlation analysis. EmoWear can be used for ER via SCG, ER during gait, multi-modal ER, and the study of IMUs for context-awareness. Targeted contextual information include emotions, gait, voice activity, and drinking, all having the potential to be sensed via a single IMU.
