Acrometastasis to hand in vaginal carcinoma: a rare entity

Although metastases to bones from solid tumors are very common, involvement of small bones of the hands is extremely rare. We report the first case of acrometastasis in vaginal carcinoma. We present a 65-year-old multiparous woman with FIGO Stage II vaginal carcinoma. The patient received treatment with external beam radiotherapy followed by brachytherapy. She had complete response to above treatment. Eleven months later, she presented with swelling on dorsum of hand. Investigations revealed metastasis to 4th metacarpal bone with lung metastasis. Hence, we present a patient with metastasis of carcinoma vagina to the 4 th metacarpal to draw the attention for the potential of such lesions to be developed in this region. It should be remembered that bone metastasis at unusual sites might be seen in vaginal carcinoma. We present this case because of its rarity and for documentation and discussion.

Role of neoadjuvant concurrent chemoradiation in locally advanced unresectable pancreatic cancer: a feasibility study at tertiary care centre

BACKGROUND

Pancreatic cancer has an extremely poor prognosis and prolonged survival is achieved only by resection with macroscopic tumor clearance. There is a strong rationale for a neoadjuvant approach, since a relevant percentage of pancreatic cancer patients present with non-metastatic but locally advanced disease. The objective of the present study was to assess the effect of neoadjuvant chemoradiation therapy (NACRT) on tumor response, down staging and resection, toxicity and any survival advantage.

MATERIALS AND METHODS

A prospective pilot study was carried out from January 2009 to June 2011 in which 15 patients of locally advanced unresectable pancreatic cancer were included. All patients were treated with NACRT protocol with oral Capecitabine and 3D conformal radiotherapy (3DCRT) of 30 Gy in 10 fractions. The patients were restaged 3 to 4 weeks after the completion of NACRT and explored for resection.

RESULTS

Out of 15 patients, fourteen were evaluable. Four patients underwent surgery, 5 had partial response but remained unresectable, 2 patients had stable disease and 3 had progressive disease. Most of the toxicities were slight and were in grade 1 to 2. None of the patients developed grade 3 or 4 gastrointestinal or hematological toxicity. The median survival was 15 months for resected patients and 8.6 months for unresected patients, respectively. The 2 year actuarial overall survival was 34.6%.

CONCLUSION

All patients with locally unresectable pancreatic cancer should be offered chemoradiation therapy, in hopes of down staging the tumor for possible resection and achieving higher survival.

Erectile dysfunction and cancer: current perspective

Erectile dysfunction (ED) is one of the major but underreported concerns in cancer patients and survivors. It can lead to depression, lack of intimacy between the couple, and impaired quality of life. The causes of erectile dysfunction are psychological distress and endocrinal dysfunction caused by cancer itself or side effect of anticancer treatment like surgery, radiotherapy, chemotherapy and hormonal therapy. The degree of ED depends on age, pre-cancer or pre-treatment potency level, comorbidities, type of cancer and its treatment. Treatment options available for ED are various pharmacotherapies, mechanical devices, penile implants, or reconstructive surgeries. A complete evaluation of sexual functioning should be done prior to starting anticancer therapy. Management should be individualized and couple counseling should be an integral part of the anticancer treatment.

Impact of Immunohistochemical profiling of Glioblastoma multiforme on clinical outcomes: Real-world scenario in resource limited setting

OBJECTIVE

Intuition into the molecular pathways of glioblastoma multiforme (GBM) has changed the diagnostic, prognostic, and therapeutic approaches. We investigated the influence of various clinical and molecular prognostic factors on survival outcomes in radically treated GBM patients.

METHODS

Medical records of 160 GBM patients treated between January-2012 and December-2018 with surgery followed by post-operative external beam radiotherapy (EBRT) with/without temozolomide (TMZ) were reviewed. Immunohistochemical (IHC) assays were performed for IDH1mutation, ATRX loss, TP53 overexpression and Ki-67% index. Apart from disease and treatment-related factors' influence on clinical outcomes, the impact of IHC markers in prognostication was analyzed using appropriate statistical tests.

RESULTS

The median overall survival (OS) was 14 months. EBRT with concurrent TMZ was given to 60% of patients and 42.5% completed the standard Stupp-protocol. Significant improvements in OS was observed in patients aged ≤ 50years (2-year OS: 22.1% vs. 12.5%, p = 0.001), those who underwent gross total resection (2-year OS: 21.8% vs. 12.8%, p = 0.002), received concurrent TMZ (21.9% vs. 12.5%, p = 0.005), completed the entire Stupp-protocol (2-year OS: 23.4% vs. 6.5%, p = 0.000), and with Ki-67 index <20% (2-year OS: 23.3% vs. 11.6%, p = 0.015). On multivariate analysis, IDH1 mutation, ATRX loss, TP53 expression, and Ki-67 ≤ 20% were significant prognosticators of outcomes.

CONCLUSION

GBM patients treated with concurrent chemoradiation and those who completed the full Stupp-protocol experienced better survival outcomes. Molecular biology significantly impacts clinical outcomes and plays a key deterministic role in newer management strategies.

Primary mediastinal germ cell tumors: Survival outcomes and prognostic factors - 10 years experience from a tertiary care institute

Primary Mediastinal Germ Cell Tumor (PMGCT) is a rare and heterogeneous entity. These tumors are typically diagnosed in young adults and carry a poor prognosis. We conducted this study to evaluate the role of radiotherapy on treatment outcomes and prognostic factors in PMGCT that may allow a more adapted treatment strategy to improve survival. Case records of patients who presented with PMGCT over a period of 10-years from January-2009 to December-2019 were retrospectively evaluated. Survival analyses were calculated using Kaplan-Meier (Log-rank) method. Poor prognostic factors for survival were evaluated with Multivariate analysis using Cox-regression method. A total of 46-patients data was analyzed, the majority of the patients were males (95.7%) with a median age of 25-years (range, 17-62). Non-seminomatous histology was predominant (60.9%). Sixteen-patients (34.7%) presented with complications at their initial presentation. Majority of the patients were treated with multimodality approach using chemotherapy, surgery, and/or radiotherapy. At a median follow-up of 40.8 months, the 1, 3, and 5-year overall survival (OS) was 69.6%, 52.2%, and 44.7% respectively. Patients who received radiotherapy in first-line treatment showed significant improvement in 5-year OS (72% vs 30%, p = 0.004) and disease-free survival (70% vs 24%, p = 0.007) in comparison with patients who did not receive. Multivariate analysis revealed that radiotherapy, chemotherapy, surgery, and complications at presentation were independent prognostic factors for OS. PMGCTs are aggressive neoplasms especially in patients presenting with disease-related complications. Dual modality management (radiotherapy as local therapy along with chemotherapy) had shown improvement in survival.

Dosimetric comparison of vaginal vault ovoid brachytherapy versus intensity-modulated radiation therapy plans in postoperative patients of cervical carcinoma following whole pelvic radiotherapy

INTRODUCTION

Dosimetric study to compare high dose rate (HDR) vaginal vault ovoid brachytherapy plan versus intensity-modulated radiation therapy (IMRT) boost plan for doses delivered to target volume and organs at risk (OAR) in postoperative patients of cervical carcinoma following whole pelvic radiotherapy (WPRT).

MATERIALS AND METHODS

Fifteen postoperative patients of cervical carcinoma suitable for vaginal ovoid brachytherapy following WPRT of 46 Gy/23 fractions/4.5 weeks were included. All were treated with brachytherapy (two sessions of 8.5 Gy each). The equivalent dose for IMRT was calculated by computing biologically effective dose of brachytherapy by linear quadratic model. Dose of brachytherapy (two sessions of 8.5 Gy) was equivalent to IMRT dose of 26 Gy/13 fractions. Doses to target volume and OAR were compared between HDR and IMRT plans.

RESULTS

Target volume was well covered with both HDR and IMRT plans, but dose with brachytherapy was much higher (P < 0.05). Mean doses, doses to 0.1, 1, 2, and 5cc, 1/3 (rd) , 1/2, and 2/3 (rd) volume of bladder and rectum were significantly lower with HDR plans.

CONCLUSION

In postoperative patients of cervical carcinoma, HDR brachytherapy following WPRT appears to be better than IMRT for tumor coverage and reducing dose to critical organs.

Dose escalation by intensity-modulated radiotherapy boost after whole pelvic radiotherapy in postoperative patients of carcinoma cervix with residual disease

AIMS

External beam radiotherapy followed by brachytherapy is the standard treatment for patients with carcinoma cervix. However, for patients who come from peripheral hospitals after incomplete surgery, whole pelvic radiotherapy (WPRT) followed by boost with either vaginal vault brachytherapy if suitable or further external beam radiotherapy is recommended. This study was conducted to evaluate if it was possible to give a higher tumour dose using intensity-modulated radiotherapy for that group of patients who were not suitable for high dose rate vaginal vault brachytherapy because of gross disease after WPRT.

MATERIALS AND METHODS

A prospective study was carried out from 2005 to 2010 in which 25 postoperative patients of cervical carcinoma with gross residual disease after WPRT of 46 Gy/23 fractions/4.5 weeks were included. Nine patients were treated with 20 Gy to the planning target volume and 30 Gy to the clinical target volume in 10 fractions; 16 patients were treated with 30 Gy to the planning target volume and 35 Gy to the clinical target volume in 15 fractions. The end points of this study were local control, survival and treatment-related toxicity.

RESULTS

The median follow-up was 38 months. The 3 year local control, progression-free survival and overall survival rates were 76, 74 and 67%, respectively. Late grade 2 rectal toxicity was seen in 11 patients. Grade 2 bladder toxicity occurred in two patients and grade 3 bowel toxicity in two patients. No other grade 3 or higher toxicity was seen.

CONCLUSION

Inadequate and inappropriate surgery in invasive cervical cancer with resulting gross residual disease is common in India. It is possible to escalate the tumour dose by intensity-modulated radiotherapy boost after WPRT in postoperative cervical carcinoma patients with gross residual disease with low incidence of severe toxicity and excellent local control.

Multimodality treatment for Central Nervous System Germ Cell Tumors: Disease spectrum and management strategies - A tertiary care center experience from India

OBJECTIVE

Intracranial germ cell tumors (GCTs) are relatively rare neoplasms, representing 2-3 % of paediatric brain tumors in Western countries and 8-15 % in East Asia. Here, we discuss the clinical features and treatment outcomes in patients with central nervous system (CNS) GCTs treated at our institute.

METHODS

Medical records of all primary CNS GCT patients were retrieved retrospectively from 2007 to 2019. Demographic, clinical, treatment and follow up details were entered in a predesigned proforma. Overall survival (OS) and progression-free survival was computed using Kaplan-Meier method and Log-Rank test. Effect of various prognostic factors on survival outcomes was assessed by univariate and multivariate analysis.

RESULTS

A total of 28 CNS GCT patients were included in this analysis. Median age at presentation was 17 years (range, 7-45 years) with a male to female ratio of 1.8:1. Pineal region was the commonest location, encountered in 15 patients (53.6 %). Pure germinoma was the most frequent histology observed, seen in 19 patients (67.9 %). Male gender and germinoma histology were highly associated with pineal location (p = 0.043 and p = 0.052, respectively). Fourteen patients underwent surgical intervention and nine patients underwent biopsy for diagnostic purpose or to relieve the obstructive symptoms. Only 23 patients (82.1 %) received chemotherapy. However, all patients received radiotherapy (Craniospinal irradiation/whole brain radiotherapy/whole ventricular radiotherapy/ or local radiotherapy). After a median follow-up of 53 months (range, 7-150), 23 patients (82.1 %) were alive. OS was significantly affected by histology (89 % in germinoma vs. 60 % in non-germinomatous, p = 0.054) and location (93 % in pineal region vs. 64.2 % in other location, p = 0.042). Age, gender and surgery did not have any impact on the survival outcomes.

CONCLUSION

CNS GCTs are relatively rare and heterogeneous neoplasms commonly seen in pineal and suprasellar locations. A combination of chemotherapy and radiotherapy had shown excellent outcomes.

Dosimetric evaluation and clinical outcome in post-operative patients of carcinoma vulva treated with intensity-modulated radiotherapy

BACKGROUND

To compare dosimetric parameters of intensity-modulated radiation therapy (IMRT) with 3D conformal radiotherapy (3DCRT) in post-operative patients of vulvar cancer and to assess clinical outcome and toxicity with IMRT.

MATERIALS AND METHODS

A total of 8 post-operative patients of vulvar cancer were treated with IMRT. All patients were also planned by 3DCRT for comparison with IMRT. The two plans were compared in terms of conformity index, homogeneity index, tumor control probability (TCP) and normal tissue complication probability (NTCP) for the planning target volume and organs at risk (OAR).

RESULTS

IMRT resulted in significantly lesser doses to rectum, bladder, bowel and femoral head as compared with 3DCRT plans. Mean conformity and homogeneity indices were better and within range with IMRT. The TCP was comparable between the two treatment plans and NTCP for rectum, bladder, bowel and femoral head was significantly less with IMRT as compared with 3DCRT. Treatment was well-tolerated and none of the patients developed Grade 3 or higher toxicity.

CONCLUSION

IMRT yielded superior plans with respect to target coverage, homogeneity and conformality while lowering dose to adjacent OAR as compared with 3DCRT. Thus, IMRT offers a reduction in NTCP while maintaining TCP.

Real world clinical outcomes of adjuvant sequential chemoradiation in patients with gallbladder carcinomas with poor performance status

PURPOSE

The purpose of the study is to analyze the overall survival, relapse-free survival, and relapse patterns of adjuvant sequential chemoradiation for gallbladder cancers after curative resection in patients with poor performance status.

MATERIALS AND METHODS

We retrospectively reviewed clinical records of gallbladder patients with pathologic stage T2-4 or node positivity treated with sequential chemoradiation at our institute between January 2015 and January 2019. Sequential chemoradiotherapy protocol consisted of six cycles of gemcitabine 1,000 mg/m2 and oxaliplatin 100 mg/m2 administered every 2 weekly and postoperative radiation therapy (45 Gy in 25 fractions over 5 weeks) by three-dimensional conformal technique.

RESULTS

A total of 36 patients were included. The median overall survival and relapse-free survival was 26 months (95% confidence interval [CI], 21.4-30.5) and 21 months (95% CI, 11.8-30.1), respectively. The 2-year overall and relapse-free survival rates were 55.1% (95% CI, 37.9%-72.3%) and 44.7% (95% CI, 27.5%-61.9%), respectively. Locoregional, systemic, and combined recurrence were noted in 2 (5.5%), 14 (38.8%), and 3 (8.3%) patients, respectively. On univariate analysis, tumour grading significantly influenced relapse free survival; nodal stage and overall stage demonstrated a statistically significant influence on overall survival (p < 0.05) with a trend towards significance for lymphovascular invasion. On multivariate analysis, no significant factors were found. Grade 3 and 4 haematological adverse events were observed only in 2 (5.5%) with chemotherapy. No grade 3 and 4 adverse events were observed due to radiation therapy.

CONCLUSION

Sequential chemoradiation is feasible and tolerable with acceptable efficacy in the adjuvant setting in patients unfit for concurrent chemoradiotherapy.

Mucoepidermoid carcinoma of the trachea in a 9-year-old male child: case report and review of literature

Mucoepidermoid carcinoma (MEC) is most common malignancy of minor salivary glands in adults. Pulmonary MEC is extremely uncommon comprising of only 0.1%-0.2% of the primary lung malignancies and <1% of primary bronchial tumors. It is even rarer in children and literature limited to few case reports only. Here we present a case report of a 9-year-old boy diagnosed with primary MEC of trachea along with review of the literature. A 9-year-old male child presented with complaint of dry cough for two years which was later associated with shortness of breath after one year. Bronchoscopic examination revealed a growth arising from right lateral wall of carina occluding 50% of the lumen and detailed histopathological examination revealed it to be a MEC of the trachea. Patient underwent local excision of the tumor with primary anastomosis. In view of positive margins adjuvant radiotherapy of 60 Gy in 30 fractions were given to the tumor bed. Patient tolerated the treatment well and is disease free at 6 months follow-up. Experience with MEC of the trachea in children is limited and optimal treatment protocols have not been defined, with current treatment mainly extrapolated from MEC of the salivary glands.

Apropos of a case of cutaneous metastasis from laryngeal cancer with review of literature

Cutaneous metastasis from laryngeal carcinoma is a rare occurrence. A 55-year-old male patient with supraglottic cancer was treated with concurrent chemoradiation. Eighteen months later, he presented with ulceroproliferative growth on dorsum of the right hand. Biopsy revealed metastatic squamous cell carcinoma. Further investigations revealed underlying bone destruction with lung metastasis. In view of poor general condition and widespread dissemination of disease, palliative radiotherapy was delivered to the hand of the patient. He achieved satisfactory palliation in form of pain relief, control of bleeding, and discharge. The present report serves to emphasize the importance of properly diagnosing metastatic spread to unusual sites. Such metastasis is rare and is associated with a poor prognosis. Treatment is usually aimed at providing pain relief in these patients with limited life expectancy. Hence, we present a case of extensive cutaneous metastasis from laryngeal carcinoma with review of the literature.

Ovarian Small Cell Carcinoma of Hypercalcemic Type in an Adolescent Girl

OBJECTIVE

Small cell carcinoma of ovary, hypercalcemic type is a rare malignancy with a dismal prognosis. The diagnosis is often confused with many other tumors.

CASE REPORT

We describe a rare case of ovarian small cell carcinoma of hypercalcemic type in an adolescent. She presented with abdominal pain, awareness of mass and vomiting. She underwent exploratory laparotomy and right ovarian excision. The detailed histopathological examination including immunohistochemistry was suggestive of ovarian small cell carcinoma of hypercalcemic type. She had progressive disease on chemotherapy and ultimately died within 2 years of diagnosis. Due to rarity of this neoplasm and its aggressive nature, the optimal treatment regimen has not been established.

CONCLUSION

We report this case because of its rare occurrence leading to clinical and diagnostic challenges and need to explore effective treatment options to improve survival in these patients.

Primary retroperitoneal squamous cell carcinoma: a literature review

PURPOSE

Retroperitoneal squamous cell carcinoma is an extremely rare histological variant of retroperitoneal tumors. The exact etiology and origin of the same is still unknown. To date, only a few case reports have been published in the literature. Due to rarity, standard treatment protocol is not available. The article aims to review the literature and treatment options available for this uncommon entity, based on available data.

METHODS

We searched the databases like PubMed, PubMed Central, Scopus, and Google Scholar with the keywords "Squamous cell carcinoma" and "retroperitoneal tumors". Peer-reviewed and recent articles were screened.

RESULTS

Seven relevant articles comprising 14 cases were found. Due to the small number of reports, tabulation of treatment details and outcome was done. Like the sarcoma variant, these tumors also present with a large mass in the abdomen and abdominal discomfort. Association with human papillomavirus appears to be the most common factor that gives rise to squamous histology.

CONCLUSION

Retroperitoneal SCC is an uncommonly diagnosed entity. Although no specific treatment guidelines exist for this uncommon malignancy; surgery followed by adjuvant or definitive radiotherapy with concurrent chemotherapy (in inoperable cases) seems a feasible option. Multicentre trials should be conducted for establishing definitive treatment strategies for this ailment.

Sphincter preservation in anal cancer: a brief review

Management of anal cancer is a challenge. The goal of treatment is to eradicate tumor without sacrificing the anal sphincters. The idea of organ preservation emerged following the discovery of a high complete response rate from preoperative combined chemoradiation (CRT) prior to abdominoperineal resection.CRT is widely accepted as the standard therapy for treating anal squamous cell cancer. The combination of external beam radiotherapy with interstitial brachytherapy increases the dose to the tumor volume and decreases dose to normal tissues. The current goal is to avoid colostomy, and surgery has become a salvage or secondary therapy. In this article, we review the non-surgical management of anal cancer with special emphasis on CRT, role of intensity modulated radiation therapy and brachytherapy.

Expanding role of radiotherapy in adenoid cystic carcinoma of the tracheobronchial tree: a new horizon

BACKGROUND

Primary adenoid cystic carcinomas (ACCs) of central trachea-bronchi system are rare and heterogeneous tumors. Definitive radiotherapy (RT) is the recommended treatment in surgically unresectable or incomplete resection or in the presence of severe comorbidities.

OBJECTIVE

To evaluate the clinical features and outcomes of patients with ACC of trachea-bronchi treated with radiotherapy.

METHODS

Retrospective medical records review was done in all patients with histologically confirmed ACC of trachea-bronchi between January 2010 and December 2019. Patient disease and treatment characteristics and toxicity data were analyzed. Overall survival (OS), local recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were computed using Kaplan-Meier method (log-rank test).

RESULTS

Nineteen patients (10 women and 9 men) were included in this analysis with median age of 40 years (range, 14-70). Of these patients, 63.2% (n = 12) presented in stage IV disease. Twelve and three patients received definitive (median dose 67.8 Gy) and adjuvant (median dose 50 Gy) RT, respectively. The median follow-up was 42.5 months (range, 4-120); 15 patients were alive and 4 were dead at that time. Local recurrence or progression was observed in 52.6% and distant metastasis found in 47.3% of patients. The 5-year OS, LRFS, and DMFS for all patients were 81.2%, 52.8%, and 39.6%, respectively. Baseline lymph node involvement showed significant impact on OS (56.3% vs 100%, p = 0.011). Among patients receiving definitive RT, patients with higher RT dose (⩾66 Gy) had significantly better survival outcomes (5-year LRFS: 75% vs 16.7%, p = 0.013).

CONCLUSION

Definitive RT is an exemplary treatment for unresectable disease. Higher dose is recommended to improve long-term outcomes.

Embryonal tumors with multilayered rosettes: A tertiary care centre experience

BACKGROUND

Embryonal tumors with multilayered rosettes (ETMR) is an extremely rare and highly aggressive tumor. It includes three distinct entities i.e, embryonal tumor with abundant neuropil and true rosettes (ETANTR), ependymoblastoma (EBL) and medulloepithelioma (MEPL). Here, we present our institutional experience of seven ETMR cases treated over a period of five years.

MATERIALS AND METHODS

Patients' records from 2015 to 2019 were reviewed manually and electronically to retrieve the data. Clinicopathological and outcome details of ETMR cases were entered in a predesigned proforma.

RESULTS

A total of seven cases of ETMR were registered from 2015 to 2019 with a median age at presentation of four years (range 3-7 years). All patients underwent surgery. However, only three patients completed the planned adjuvant treatment, comprising of focal radiotherapy (RT) alone, craniospinal irradiation (CSI) alone and CSI followed by six cycles of chemotherapy in one patient each respectively. Two patients commenced CSI but deteriorated during RT and thereafter needed best supportive care. Two patients could not be started on any adjuvant treatment. Unfortunately, six patients succumbed to their disease within one year of their diagnosis. Only one patient who received both CSI and adjuvant chemotherapy is alive at 15 months of diagnosis.

CONCLUSION

ETMR is a rare and aggressive entity. Majority of the patients die within one year of the diagnosis despite multimodality treatment.

Comparative analyses of paclitaxel/carboplatin with cisplatin/5-fluorouracil-based chemoradiation in locally advanced inoperable upper and middle third esophageal cancer: A randomized prospective pilot study

INTRODUCTION

Chemoradiation therapy (CRT) remains the treatment of choice for inoperable locally advanced esophageal cancer (LAEC). Several CRT regimens are existent in esophageal cancer, but definitive conclusions are lacking. We performed a pilot study to compare treatment outcome, survival, and toxicities in inoperable upper and middle third esophageal cancer patients undergoing CRT using either paclitaxel/carboplatin or cisplatin/5FU based regimen.

METHODS

Patients were randomised in two arms (arm A and arm B). In Arm A, taxane-based (Paclitaxel+carboplatin) and in arm B non-taxane-based (cisplatin+5FU) doublet chemotherapy drugs were given concurrently with external beam radiation therapy (EBRT). EBRT in two phases up to a total dose of 54 Gy/27#@2Gy/# was given. Response was subsequently assessed using Response evaluation criteria in solid tumors (RECIST v1.1) and toxicities utilizing Common Terminology Criteria for Adverse Events (CTCAE v 4.0).

RESULT

The overall response rate (ORR) in the taxane-based group was higher than the non-taxane-based group, but was not significantly different (p=0.851). Regarding hematological toxicities, anaemia and reduced cell counts were more in the taxane group compared to the non-taxane group while non-hematological toxicities were comparable. Similarly, better survival with late toxicities were seen with taxane-based arm when compared to non-taxane-based arm, though it was not statistically significant.

CONCLUSION

Our pilot analysis highlights the fact that paclitaxel/carboplatin CRT shows better response, survival, and comparable toxicities when compared to cisplatin/5FU, though statistically nonsignificant. Further randomised prospective trials with large sample size are warranted.

Rare Case of Primary Pulmonary Pleomorphic Liposarcoma Treated With Multimodal Therapy

Background: Pleomorphic liposarcoma (PLS) is a very rare type of primary pulmonary sarcoma. Clinical data about these tumors are limited, and optimal treatment has not yet been defined. Case Report: A 32-year-old male presented with pain and heaviness over the right chest. Contrast-enhanced computed tomography (CECT) of the chest showed a heterogeneous hypodense pleural-based mass and a mediastinal mass. The patient was treated with chemoradiotherapy, followed by excision and adjuvant chemotherapy. Seven months after completion of treatment, he presented with an abdominopelvic mass and soft tissue peritoneal deposits. The mass was resected, and second line chemotherapy resulted in a partial response. The patient was routinely followed. Six months after completion of the second round of chemotherapy, CECT showed multiple soft tissue deposits in the right lumbar region, right hemipelvis, and presacral region with no evidence of pulmonary disease. Chemotherapy elicited a partial response. Three years from the date of diagnosis, the patient was alive with stable disease. Conclusion: This case is unique because of the rare primary site of PLS presentation and the rare presentation of peritoneal metastasis. Citing such cases would help us to define adequate treatment protocols for this aggressive tumor.

Recurrent angiosarcoma of scalp with opsoclonus myoclonus syndrome: role of salvage treatment

Cutaneous angiosarcoma is a type of rare and locally aggressive malignancy requiring individualised treatment owing to paucity of randomised trials. We present the case of a middle-aged cancer survivor with locally advanced angiosarcoma of scalp managed with surgery, radiotherapy, chemotherapy and targeted therapy over a course of 6 years for two recurrences. The first recurrence was preceded by opsoclonus myoclonus syndrome, a type of paraneoplastic neurological syndrome (PNS), rarely reported in sarcomas. The second recurrence had a rapid clinical course, which led to a therapeutic dilemma of best supportive care versus active management. A trial of weekly paclitaxel was started that was continued for a total of 12 cycles with good objective clinical response. Presently, he is tolerating maintenance pazopanib well and is symptom free for 6 months. In cutaneous angiosarcoma patients, PNS may be a harbinger of recurrence and aggressive, multimodality treatment helps prolong survival.
