Safety and efficacy of Oro-T oral rinse in oral mucositis during cancer radiotherapy and/or chemotherapy: Cumulative analysis of two studies.

INTRODUCTION: Oral mucositis is inflammation of the mucosa of the mouth which ranges from redness to severe ulceration. It results from the local effects of radiation to the oral mucosa. OBJECTIVES: The study is cumulative analysis of two studies (one comparative and the other open labeled) evaluated in individuals with oral mucositis during cancer radiotherapy and/or chemotherapy for the safety and efficacy of Oro-T mouthwash in a comparative design with normal saline. METHODOLOGY: Both the studies were similar with respect to clinical and laboratory parameters for analysis. The participants were advised to use 10 ml of Oro-T for 1 min 4 times daily for 6 weeks starting from day 1 of standard care. Patients were followed up, and the results were assessed from baseline on visit days: At entry and at the end of every week for 6 weeks. Clinical assessment of oral condition was done objectively (by the investigator) and also subjectively. Clinical symptoms such as sore throat, number of ulcer, burning sensation, pain, difficulty in chewing, difficulty in drinking, and mucositis grading along with Patient Reported Outcome Measures Scale were evaluated at each interval. Data was available for 40 subjects in Oro-T and 15 subjects in NS groups respectively. RESULTS AND CONCLUSION: The significant positive outcome was reported both subjectively and objectively in Oro-T group as compared to NS group with the delay in the onset of symptoms and less severe manifestation of oral mucositis with an improvement in quality of life. No adverse effects were reported that prompted discontinuation of study medication. Overall compliance to study medication was good.

Brachytherapy for Oral Cavity Cancers in the Era of Intensity-Modulated Radiotherapy: Save it or Shelve it.

Head and neck cancer treatment includes a multidisciplinary approach involving all specialties. Surgery and radiotherapy are equally effective in controlling small tumors. Intensity-modulated radiotherapy (IMRT) and interstitial brachytherapy (ISBT) play an important role in the treatment of head and neck cancers. Both are proved to be highly conformal techniques of radiotherapy. Our aim is to compare dosimetric aspects of ISBT alone, IMRT alone, and IMRT combined with ISBT in early stage node negative oral cavity cancer. Ten cases of histopathologically proven early stage node negative oral cavity cancer were treated with external beam therapy followed by interstitial brachytherapy boost or ISBT alone. All these patients had undergone computerized tomography (CT) planning for brachytherapy. Retrospectively, these images were utilized, and three sets of plans were done for each patient's CT image set. Group A was IMRT alone plans, groups B had combined IMRT with ISBT boost, and group C was ISBT alone plans. Dosimetric details such as target coverage, dose to critical organs, and conformity index were compared between the three sets of plans. The mean values of the doses to the critical organs with IMRT alone and IMRT with ISBT boost were brainstem 10.40 Gy and 9.20 Gy, spinal cord 19.20 Gy and 16.10 Gy, mandible 62.99 Gy and 66.50 Gy, and I/L and C/L parotids were 6.03 Gy and 5.50 Gy and 5.70 Gy and 5.10 Gy where as in ISBT alone plans mean values were brainstem 1.30 Gy, spinal cord 1.40 Gy, mandible 36.50 Gy, I/L, and C/L parotids were 1.60 Gy and 1.00 Gy. Conformity index (CI) between IMRT and ISBT plans were 0.8580 and 0.7140 respectively. With comparable CI values, doses to critical organs appear to be in favor of ISBT plans as opposed to IMRT, and this was found to be statistically significant. Brachytherapy shows a dosimetric advantage over IMRT in this setting and could be translated to a benefit in terms of toxicities, organ preservation, and cosmesis in the actual clinical scenario. However, whether this would translate to significant benefit in terms of clinical outcome needs to be still verified.

Tolerance of Radical Radiotherapy Among Elderly Head and Neck Cancer Patients.

Head and neck cancers usually occur in the elderly age group and about half of the cases occur at the age > 60 years with majority detected in an advanced stage with increased morbidity and decreasing compliance to therapy. Since there are limited data available for the adequate treatment of elderly head and neck cancer patients, we proposed a study to analyze tolerance and response based on age, site, modality of treatment received, and implication of nutrition vs weight loss during treatment. Fifty-five patients were enrolled in this study, which was conducted between November 2015 and April 2017, and those who met the eligibility criteria were evaluated with a detailed history and physical examination, and biochemical, pathological, and radiological investigations. Patients were staged based on TNM staging and treated as per the standard guidelines. Patients were assessed with the weekly routine blood investigation, weight loss, and toxicity. The response was assessed after 6 weeks and documented as per RECIST criteria. 52/55 (94.5%) patients completed the treatment, and 48/55 (92.3%) had a complete response at 6 weeks (p value 0.000) with a mean treatment duration of 46.67 days and mean weight loss of 5.44 kg with 55.4% having GR-II mucositis, 40% having GRIII mucositis at the time of completion of treatment. Sixty-eight percent having GRII and 38.2% having GR I dermatitis and 80% had moderate pain. Subgroup analysis was done based on age, site, and treatment modality. Patients were also assessed for nutrition vs weight loss. We concluded that elderly patients tolerate and respond well to radical treatment with acceptable toxicities; hence, age should not be a barrier to decide treatment.

Adjuvant radiotherapy in carcinoma buccal mucosa; more conformal the best: Is it so?

INTRODUCTION: Since 1980s, computerization has made improvements in radiation therapy delivery from conventional two-dimensional to three-dimensional conformal radiotherapy (2DCRT to 3DCRT) to intensity-modulated radiotherapy (IMRT) and its newer versions. This small study is aimed to compare the existing techniques for planning target volume (PTV) and organ at risk (OAR) dose distribution parameters in postoperative buccal mucosa cases. MATERIALS AND METHODS: Ten post operative cases of early stage carcinoma buccal mucosa in whom only post operative bed irradiation was indicated was enrolled and was planned with conventional, 3DCRT and IMRT techniques to get 95% PTV coverage and dose received by organs at risk were recorded and evaluated. RESULTS: Mean and standard deviation values for PTV 95% for IMRT, 3DCRT, and conventional plans were 96.4 ± 1.8, 95.1 ± 1.9, and 91 ± 2.7, respectively. Dose received by OARs was high in conventional technique when compared to the other two. Maximum dose received by 1 cc of brain (46.2 ± 7.9 and 60.8 ± 3.8) (priority was given for PTV coverage) and mean dose received by the same eye (13.6 ± 1.4 and 22 ± 2.4) were less in IMRT when compared to 3DCRT. However, maximum dose received by 1 cc of brainstem (29.7 ± 7.6 and 14.1 ± 9.5), optic chiasma (29.2 ± 4.2 and 12 ± 2.1), spinal cord (31.8 ± 3 and 20.9 ± 4.2), and the same-side optic nerve (22 ± 6.9 and 11.7 ± 9.4) and mean dose received by opposite-side parotid (8.7 ± 1.1 and 1.7 ± 0.4) and submandibular gland (18.6 ± 1.7 and 3.2 ± 0.9) were more with IMRT when compared to 3DCRT. CONCLUSION: In postoperative cases of early-stage carcinoma buccal mucosa, it is good enough to treat with 3DCRT technique. Here, the target area will be well lateralized, and 3DCRT technique can give good target coverage and less dose to OARs, especially the only remaining major salivary glands.

Optimal technique of radiotherapy for carcinoma cervix in developing countries: Dosimetric and logistic comparison.

PURPOSE: Carcinoma cervix is the most common malignancy affecting women in developing countries. Radical radiotherapy is the mainstay of treatment in more than 90% of patients. The present study is a dosimetric and logistic comparison of various techniques of radiotherapy, namely two-dimensional conventional radiotherapy (2DCRT), three-dimensional conformal radiotherapy (3DCRT), and intensity-modulated radiotherapy (IMRT). METHODS: All the patients underwent contrast-enhanced computed tomography (CT) scans for simulation. 2DCRT, 3DCRT, and IMRT plans were generated in 24 patients and dosimetrically compared. Radiotherapy treatment time involved in each technique was analyzed in 27 treated patients. RESULTS: The planning target volume (PTV) coverage was best in 3DCRT technique with a median coverage of 99.9% as compared to IMRT (99.3%) and 2DCRT (82.2%). There was progressive sparing of all the organs at risk in IMRT as compared to 3DCRT. The total planning time was longest in IMRT (332.1 min) and shortest in 2DCRT (11.7 min). The mean treatment time for the delivery of each fraction of 2DCRT, 3DCRT, and IMRT were 14.3, 13.6, and 24.7 min, respectively. CONCLUSION: 3DCRT technique is the most optimal technique for radical radiotherapy of cervical cancers with optimum PTV coverage, acceptable planning time, and minimal treatment time as compared to IMRT. 2DCRT technique should be limited to the setting where CT simulation is unavailable.

Carcinoma esophagus with xeroderma pigmentosa: Case report on a rare association.

Radiation in patients with diseases such as xeroderma pigmentosa (XP), systemic lupus erythematosus, and other connective diseases is a matter of concern because of higher incidence of toxicities. Here with, we are reporting a case of carcinoma esophagus with XP, who tolerated the treatment well with sufficiently prolonged palliation of symptoms, after treatment with external beam radiotherapy. This might be attributed to the different mechanisms of DNA damage and repair mechanisms for ultraviolet (UV) rays and X-rays. UV rays cause DNA damage by dimer formation whereas X-rays will cause single- or double-stranded breaks in DNA. The repair mechanisms for UV rays are nucleotide excision repair and translesion synthesis while for X-rays, they are base excision repair, homologous recombination, and nonhomologous end joining, and these repair mechanisms for X-rays are intact in a XP patient. Hence, they can be been treated with high dose of radiation, and they do tolerate the treatment well.

Quantification of Dose-Volume and Dose-Length Parameters for Cervical Esophageal Stricture in Head and Neck Irradiation with the 3DCRT and IMRT Technique.

PURPOSE: To quantify and compare dose-volume and dose-length parameters of cervical esophagus between three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiation therapy (IMRT) and to correlate with incidence of cervical strictures in head and neck cancer irradiation with radical intent. MATERIALS AND METHODS: Forty consecutive head and neck cancer patients who received radical radiation therapy, either with 3DCRT (n = 20) or IMRT (n = 20), between December 2011 and August 2012 were retrospectively analyzed and followed up for at least 4 years post-treatment completion. RESULTS: The volumes of cervical esophagus receiving ≥54 Gy (V54) and ≥60 Gy (V60) and lengths receiving circumferential dose of ≥50 Gy (L50) and ≥54 Gy (L54) were significantly higher in patients treated with IMRT as compared to 3DCRT (P ≤ .05). At the end of minimum 4 years' post-treatment, nine patients had documented symptomatic strictures; three patients were treated with 3DCRT and six patients with IMRT technique. CONCLUSION: IMRT technique in entire-neck irradiation is associated with increased spillage dose to the cervical esophagus, and thereby increased risk for late sequelae. The cervical esophagus has to be considered as an organ at risk and constraints need to be given in IMRT planning, particularly for lower-neck irradiation.

Accelerated Radiation Therapy Using Weekend Boost with Concurrent Cisplatin in Head and Neck Squamous Cell Cancers: An Indian Institutional Experience.

PURPOSE: The purpose of the study was to evaluate the feasibility and efficacy of an accelerated radiotherapy schedule using weekend boost in terms of tumor response, compliance, and acute toxicities for head and neck squamous cell carcinoma, and to report long-term clinical outcomes. MATERIALS AND METHODS: Twenty-six patients with stages III-IV head and neck squamous cell carcinoma receiving radical chemoradiotherapy were accrued prospectively into the study. External beam radiation therapy to a total dose of 66-70 Gy in 33-35 fractions, 1.8-2.0 Gy per fraction along with concurrent weekly cisplatin was planned. Radiation regimen included delivery of six fractions per week, with boost field delivered as the sixth fraction on the weekend. The compliance, tumor response, and toxicities were recorded. Survival curves were estimated using the Kaplan-Meier method. RESULTS: Twenty-one of 26 patients (81%) completed treatment as planned and five patients died during the course of treatment. Sixteen patients (62%) completed treatment in less than 44 days and, at the end of 3 months' follow-up, 18 patients (69%) showed complete response and two patients (8%) showed partial response. The 2- and 5-year actuarial disease-free survival were 90% and 65%, respectively, and 2- and 5-year actuarial overall survival were 60% and 38%, respectively. CONCLUSION: Accelerated fractionation using weekend boost, along with concurrent weekly concurrent cisplatin, is an effective and promising approach with favorable impact on initial tumor response, comparable results, and acceptable toxicities.

Impact of Molecular Predictors on the Response Rates in Head and Neck Cancer Patients - an Observational Study.

Squamous cell carcinoma of head and neck region account for more than 25 % of male and more than 10 % of female cancers in India (1). Head and neck cancer treatment includes a multidisciplinary approach involving all specialties. Concurrent chemo-radiation is the standard of care in most of the subsites (2). Inspite of the multi-disciplinary approach, a plateau has been reached in terms of results with 5 year survival of locally advanced disease of around 30 % (3). In order to improve outcomes, there has been considerable interest in molecular profiling of head and neck cancers 4-10. However there is still significant paucity in terms of Indian data, hence the need for the study. The objectives are to assess the HPV-p16, EGFR and p53 status, to correlate HPV-p16, EGFR and p53 status with the response rates, to correlate HPV-p16,EGFR and p53 status with other factors like age, sex, tobacco use. Twenty five consecutive cases of histopathologically proven head and neck cancers were accrued. All patients were treated with external radiation to a dose of 66Gy in 33 fractions along with concurrent weekly cisplatin chemotherapy at a dose of 40mg/sqm. HPV-p16, EGFR and p53 mutation analysis was done on paraffin embedded histopathological blocks. PCR technique used for HPV-p16, EGFR and p53 status detection. Response assessment was done based on RECIST criteria. Correlation of HPV, EGFR and p53 status on response was done. The EGFR positivity rate was 84 %, the p53 positivity rate was 76 % and the HPV p-16 positivity rate was 28 %. Out of 25 patients, 13(52%) had complete response, 7(28 %) had partial response, 3(12 %) had stable disease and 2(8 %) had progressive disease. On correlation of molecular profile with response, there was no statistical significance between EGFR status and response (p 0.5) or HPV-p16 and response (p 0.8). However, p53 positivity was approaching significance with respect to good response (p 0.07).

A prospective dosimetric and clinical comparison of acute hematological toxicities in three-dimensional conformal radiation therapy and intensity modulated radiation therapy with concurrent chemotherapy in carcinoma cervix.

BACKGROUND AND OBJECTIVES: Acute hematological toxicities are an important cause of morbidity in patients receiving concurrent chemoradiation to pelvis in carcinoma cervix. The objective of this study was to evaluate the role of intensity-modulated radiotherapy (IMRT) in reducing the dose to the bone marrow as compared with three-dimensional conformal radiotherapy (3DCRT) and hence its impact on reducing the acute hematological toxicities. MATERIALS AND METHODS: Eleven consecutive patients treated with IMRT and 12 patients treated with 3DCRT to the whole pelvis along with concurrent chemotherapy were selected. Bone marrow was delineated. V10 Gy, V20 Gy, V95%, and Dmean of bone marrow were recorded. Weekly blood counts were recorded and graded as per Common Terminology Criteria version 4.0 for all the patients. RESULTS: The dose to the bone marrow V20 Gy was 206.78 ± 57.10 cc (75%) and 251.70 ± 40.45 cc (91%) for IMRT and 3DCRT, respectively (P = 0.04) and V95% was 23.30 ± 8.34% and 46.76 ± 6.71% for IMRT and 3DCRT, respectively (P = 0.001). The grade of toxicities during each week did not show the difference in either arm. However, the total count and Neutrophil counts during the 2nd week showed statistical significance between IMRT and 3DCRT. CONCLUSION: IMRT significantly reduces the dose to the bone marrow as compared to 3DCRT. The reduction of the dose did not translate into a decrease in acute hematological toxicities. Concurrent platinum-based chemotherapy is the probable cause for the hematological toxicities.

A rare case of papillary carcinoma of choroids plexus: Its management and review of literature.

Papillary carcinoma of choroids plexus is very rare. Only a few cases have been described in the literature, and it is most commonly found in the pediatric population. A further observation is added now. A 20-year-old lady presented with complaints of headache and vomiting from past one and half months, headache was increasing in severity and there was relief after vomiting. On examination, no abnormality was detected in any of her systems. The patient underwent computed tomography scan of brain, which showed space occupying lesion in the right frontal lobe. She underwent near total excision of the lesion. Postoperative period was uneventful. Histopathology was suggestive of papillary carcinoma of choroids plexus and was confirmed with immunohistochemistry. The patient received whole brain radiation and intrathecal chemotherapy. The patient tolerated the treatment well, except for grade two vomiting. She has completed one and half years of follow-up and is disease free.

How common is hypothyroidism after external radiotherapy to neck in head and neck cancer patients?

PURPOSE: To identify the occurrence of clinical and subclinical hypothyroidism among head and neck cancer patients receiving radiation to the neck and to justify routine performing of thyroid function tests during follow-up. MATERIALS AND METHODS: This is a prospective nonrandomized study of 45 patients of head and neck cancer, receiving radiotherapy (RT). Thyroid stimulating hormone and T4 estimations were done at baseline and at 4 months and 9 months following RT. RESULTS: Of the 45 patients, 37(82.2 %) were males and eight (17.8 %) were females. All patients received radiation to the neck to a dose of >40Gy. 35.6% received concurrent chemotherapy. Two patients underwent prior neck dissection. Fourteen patients (31.1%) were found to have clinical hypothyroidism (P value of 0.01). Five (11.1%) patients were found to have subclinical hypothyroidism with a total 19 of 45 (42.2%) patients developing radiation-induced hypothyroidism. Nine of 14 patients with clinical hypothyroidism were in the age group of 51 to 60 years (P=0.0522). Five of 16 patients who received chemoradiation and nine of 29 who received RT alone developed clinical hypothyroidism. Above 40 Gy radiation dose was not a relevant risk factor for hypothyroidism. CONCLUSION: Hypothyroidism (clinical or subclinical) is an under-recognized morbidity of external radiation to the neck which is seen following a minimum dose of 40 Gy to neck. Recognizing hypothyroidism (clinical or subclinical) early and treating it prevents associated complications. Hence, thyroid function tests should be made routine during follow-up.

Magnitude of fatigue in cancer patients receiving radiotherapy and its short term effect on quality of life.

BACKGROUND: Fatigue is one of the most common, ongoing symptoms reported by patients undergoing radiotherapy and has profound effects on the quality of life. AIMS: This study attempts to identify the magnitude of fatigue and its implication on the quality of life during radiotherapy. METHODS AND MATERIALS: A prospective study was conducted from March 2004 to September 2005, on 90 patients with histologically proven cancer, receiving radiotherapy. Pretreatment and weekly assessment of fatigue and QOL was done during radiation treatment using Brief Fatigue Inventory Scale and EORTC QLQ C30 respectively and repeated one month after completion of radiotherapy. All the scores were measured in the 0 to 100 scale. STATISTICAL METHODS USED: Trimean, SPSS 11.0 and Sysstat 8.0 were used for statistical analysis. RESULTS: Fatigue was present in 87.8% of patients initially and increased gradually over the course of radiotherapy and peaked in the last week. However at follow up it was nearing the pretreatment level. There was significant reduction in the functional scores ( P < 0.001) of QOL (physical, role and emotional function), which returned to pretreatment level at follow up. In the seventh week impairment of cognitive function (P=0.059) was noted. Significant reduction of social function (P < 0.001) at second week and global health status (P < 0.001) at fifth week was noted while financial difficulty was seen from second week onwards. CONCLUSION: Fatigue is transiently increased by radiotherapy before reaching pretreatment level after few weeks of completion of radiotherapy. QOL is also affected by fatigue which follows the same pattern.

Positional variation of applicators during low dose rate intracavitary brachytherapy for cervical cancer: a prospective study.

PURPOSE: In order to know the effect of variation in position of applicators to the dose received by the tumor volume, critical organs such as rectum and bladder and the correlation of variation on the clinical outcome. MATERIAL AND METHODS: 36 patients with histologically proven cervical cancer, undergoing intracavitary brachytherapy (ICBT) from October 2005 to December 2006 were the subjects of the study. Two pairs of orthogonal X-ray films were taken: one prior to loading of sources and the other after removal of sources. These patients were followed up as per the RTOG criteria. RESULTS: The median duration of insertion was 25 hours with a median follow up period of 6.7 months. The translational variation of the applicator position for all patients was 3 mm and 1 mm (2 SD), respectively, in the patient's lateral and antero-posterior direction. The rotational variation was 3 and 4 degrees (2 SD) in the patient's transverse and sagittal planes. Detailed analysis of source movement showed following changes in median dose: point A: 14%, point B: 2%, point P: 1%, Rectum 1: 3.5%, Rectum 2: 4% and Bladder: 9.1%. The incidence of rectal toxicity was 6/36 (16.7%) and that of bladder was 1/36 (2.8%). When the variables were grouped to evaluate the relationship, our study showed statistically significant relationship between: R2 and rectal toxicity (p value: 0.002), point A and rectal toxicity (Pearson: 0.792), lateral displacement/anteroposterior displacement and rectal toxicity (p value: 0.012/0.003), beta angle and R2 (p value: 0.002). CONCLUSIONS: The geometric relationships between the ICBT applicators and the critical structures vary during the course of low dose rate brachytherapy. Source movement does result in significant dose alterations in terms of increased rate of complications, but its impact on cure rates needs to be studied in the future.

Invasive thymoma with intraorbital metastases.

Thymomas are epithelial neoplasm of thymus and most common primary neoplasm of anterior and superior mediastinum affecting males and females equally. It occurs usually in the fifth to seventh decade. Approximately one-third of thymomas are invasive. Metastases to distant extrathoracic sites such as the liver, lung, lymph node, kidneys, ovary and brain occur infrequently. This is more common with invasive thymomas. Although brain has been shown to be a site of infrequent metastases, intraorbital metastases has not yet been reported. Here we report one such case of invasive thymoma of anterior superior mediastinum, which later metastasized to orbit as well as the brain.

Unilateral solitary choroid metastasis from breast cancer: rewarding results of external radiotherapy.

Intraocular metastatic tumor is the commonest intraocular malignancy in adults, with uveal tract the commonest site. In nearly 85% of cases the choroid is the afflicted site due to its vascularity. Breast and lung are the common primaries. In breast primaries, this could be the first metastatic disease. This condition should always be kept in mind in patients with visual symptoms. Fundus examination, ultrasonography and CT/MRI of the orbit help in diagnosis. Early recognition and timely treatment can save the visual function thus imparting good quality of life to the patient. External beam radiotherapy is a good local form of treatment. Hormone therapy in hormone receptor positive tumors can have additional benefits. Here we report a case of unilateral solitary choroid metastasis in a case of breast cancer treated with external beam radiotherapy.

Epidural analgesia during brachytherapy for cervical cancer patients.

AIMS: To find out the efficacy of epidural analgesia in providing continuous pain relief for patients undergoing brachytherapy for cervical cancer. SETTINGS: Teaching Hospital. DESIGN: Retrospective Study. MATERIALS AND METHODS: A total of 152 patients of cervical cancer received epidural analgesia during 18 to 21 hours of pelvic brachytherapy. Epidural top up was given using 60-100 microg of buprenorphine every 08-10 hrs. Additional top up or systemic analgesics were given for breakthrough pain. RESULTS: Majority of patients 119 out of 152 received epidural top up twice during their stay in the brachytherapy ward. Only 20 out of 152 needed additional analgesics. CONCLUSIONS: Epidural analgesia is safe and provides satisfactory pain relief during brachytherapy and makes patient's stay more comfortable.

Nasopharyngeal angiofibroma treated with radiotherapy.

Nasopharyngeal angiofibroma is a rare, highly vascular, benign, locally aggressive tumor, affecting boys of adolescent age. The aggressiveness and high vascularity makes surgery and even a biopsy difficult in majority of cases. Although surgery is the treatment of choice in early cases, considerable debate exists regarding the treatment of advanced disease with intracranial extension. Radiotherapy provides a good response and also avoids surgery-associated morbidity. We are herewith reporting a case of nasopharyngeal angiofibroma who showed complete hemostasis and improvement in vision to radiotherapy.

"Primary" aggressive chondroblastoma of the humerus: a case report.

BACKGROUND: Chondroblastomas are rare epiphyseal bone tumors. Very few cases with extra-cortical aggressive soft tissue invasion or metastasis are reported. CASE PRESENTATION: We report a 28 year-old adult male who presented with a large swelling over the left shoulder region. Pre-operative imaging revealed a large tumor arising from upper end of humerus with extensive soft tissue involvement necessitating a fore-quarter amputation. Patient received adjuvant radiation. CONCLUSIONS: This patient is one of the largest chondroblastomas to be reported. Although chondroblastomas are typically benign, rarely they can be locally aggressive or metastatic. Early diagnosis and institution of proper primary therapy would prevent mutilating surgeries and recurrences.
