Reirradiation with advanced brachytherapy techniques in recurrent GYN cancers.

PURPOSE: To evaluate clinical outcomes of recurrent gynaecological cancers treated with reirradiation (reRT) using advanced brachytherapy (BT) technique. METHODS AND MATERIALS: Seventy-six women who underwent reRT with BT for gynaecological cancers at our institute between January 2000 and December 2019 were analysed to determine patient, disease and treatment characteristics and clinical outcomes. Descriptive analysis was used for demographics, and the Kaplan Meir method was used for survival analysis. RESULTS: Median age at recurrence was 55 years (Range: 35-73). Forty-three patients had recurrent cervical cancer with intact uterus, and 33 had recurrent vault/vaginal cancers post adjuvant RT. Eight patients received EBRT prior to BT (Range: 30-50Gy). Twenty-two patients (28.9%) received salvage chemotherapy before consideration of brachytherapy. Brachytherapy application was done using MUPIT in 38, Vienna applicator in 20, Syed Neblett in 8, central vaginal cylinder in 3, multicatheter intravaginal applicator in 2, tandem-ovoids in 4 and Houdek applicator in 1 patient. Median cumulative EQD2 for all courses of radiation was 108 Gy (IQR 92-123 Gy). At median follow up of 39 months, local control (LC), progression-free survival (PFS) and Overall survival (OS) at 2-years was 60%, 56.3%, and 72.9 respectively. Patients who had recurrences beyond 2 years had significantly better OS compared to early recurrences. Patients who received BT doses >40 Gy had a higher LC and PFS. Grade 3 to 4 late rectal toxicity was seen in 10 (13%), bladder toxicity in 6 (8%) and vaginal fibrosis in 24 (31%) patients. CONCLUSION: The use of advanced BT approach in reirradiation setting is a feasible and safe option in treatment of post-treatment recurrent cervical, endometrial, and vaginal cancers.

Months and Severity Score (MOSES) in a Phase III trial (PARCER): A new comprehensive method for reporting adverse events in oncology clinical trials.

Background: Adverse event reporting in oncology trials lacks temporal description. We propose a toxicity summarizing method that incorporates time. Methods: Patients recruited in a phase III trial (NCT01279135) that compared three-dimensional conformal radiotherapy (3DCRT) and intensity modulated radiotherapy (IMRT) for late toxicity in cervical cancer were included. Adverse events were reported using Common Terminology Criteria for Adverse Events (CTCAE) v3.0 and quality of life (QOL) with EORTC QLQ-C30 and CX24. A total of six symptoms with a related QOL question (diarrhoea, abdominal pain, anorexia, urinary incontinence, frequency and fatigue) were included. Month and severity score [MOSES= ∑ (CTCAE grade x proportionate time)] was calculated. Cumulative-MOSES (C-MOSES) was calculated by summating these 6 individual MOSES. QoL was categorized as "substantially symptomatic" or "not". Receiver operator curve analysis was performed to determine the MOSES cut off that predicts for substantial QOL symptoms. CTCAE and MOSES were tested for accurately categorizing QOL impact. Findings: In the construction dataset, 201/300 patients had symptoms. MOSES > 0.20 had higher accuracy than CTCAE for predicting impact on QOL related to diarrhoea (85% vs. 69%), anorexia (61% vs 51%), abdominal pain (71% vs. 57%), urinary incontinence (72% vs. 61%) and frequency (62% vs. 59%). C-MOSES > 0·70 correlated with reduction in role functioning and global QOL. While no difference was seen in CTCAE grade ≥1 Gastrointestinal (GI) toxicity between 3DCRT or IMRT arm, 3DCRT had higher C-MOSES than IMRT (HR=0.64;95% CI 0.41-0.99, p = 0.04). Interpretation: MOSES has higher accuracy than CTCAE in categorizing symptom specific and functional QOL. These results require further external validation. Funding: None.

Computed Tomography-Based Interstitial Brachytherapy for Recurrent Cervical Carcinoma in the Vaginal Apex.

AIMS: To determine the factors influencing the outcomes of patients with recurrences post-hysterectomy for cervical cancers treated with external beam radiotherapy (EBRT) and interstitial brachytherapy. MATERIALS AND METHODS: This prospective study accrued 90 patients between October 2008 and May 2014. All patients had had a prior hysterectomy and were diagnosed with recurrent vaginal apex cancers with squamous cell carcinomas. All underwent EBRT of 50 Gy (2 Gy/fraction) using tomotherapy-based image-guided intensity-modulated radiotherapy with concurrent chemotherapy of weekly cisplatin (40 mg/m2) followed by high dose rate interstitial brachytherapy boost of 20 Gy (4 Gy/fraction twice a day). Local relapse, disease-free and overall survival were determined. RESULTS: At a median follow-up of 74 months (4-123 months), 10/90 (11%) patients had local failure as the first site of relapse and 12/90 (13.3%) had first distant relapse. Only one patient had synchronous local and distant relapse. The 7-year local relapse-free, disease-free and overall survival were 87.6, 68.3 and 68.3%, respectively. Grade 2 and 3 rectal toxicity were seen in 5.6 and 3.1% of patients, respectively. Among these, two (2.2%) patients underwent temporary diversion colostomy due to vaginal sigmoid and rectovaginal fistula. Grade 2 and 3 bladder toxicity were seen in 5.6 and 1.1% of patients, respectively. In summary, the lateral disease extent (P = 0.048) and the presence of nodal disease at diagnosis (P = 0.08) had a statistically significant or borderline impact on local relapse without any impact on disease-free survival. Tumour size in itself did not affect overall survival. CONCLUSION: With the integration of EBRT and interstitial brachytherapy, most vaginal apex recurrences can be salvaged. An excellent local control and survival is achievable using intensity-modulated radiotherapy with image guidance and concurrent chemotherapy followed by high dose rate interstitial brachytherapy.

Paratesticular Paraganglioma.

Paratesticular paragangliomas are a rare occurrence. We present the case of a 43-year-old man who presented with paresthesia and paraparesis and was found to have pathologic fracture involving D1 vertebra as a manifestation of metastasis from a nonsecretory right paratesticular paraganglioma.

Global Collaborations for Cervical Cancer: Can the East-West Alliance Facilitate Treatment for all?

Despite the advances in the primary prevention of cervical cancer, there is an absolute increase in the incidence of cervical cancer as a result of an increase in world population. A vast majority of patients in low and low-middle income countries continue to present at a locally advanced stage, necessitating treatment with chemoradiation and brachytherapy. There is a dearth of equipment and trained professionals for the treatment of cervical cancer, especially in low and low-middle income countries. There is an urgent need to improve treatment availability and develop better treatments. Worldwide trends, however, reveal a low number of therapeutic and innovative research trials in cervical cancer. The present article elucidates the existing challenges and provides solutions to improve outcomes. The proposed strategies hinge on strengthening collaborations for global advocacy.

An Audit for Radiotherapy Planning and Treatment Errors From a Low-Middle-Income Country Centre.

AIMS: To report the findings of an audit for radiotherapy errors from a low-middle-income country (LMICs) centre. This would serve as baseline data for radiotherapy error rates, their severity and causes, in such centres where modern error reporting and learning processes still do not exist. MATERIALS AND METHODS: A planned cross-sectional weekly audit of electronic radiotherapy charts at the radiotherapy planning and delivery step for all patients treated with curative intent was conducted. Detailed analysis was carried out to determine the step of origin of error, time and contributing factors. They were graded as per indigenous institutional (TMC) radiotherapy error grading (TREG) system and the contributing factors identified were prioritised using the product of frequency, severity and ease of detection. RESULTS: In total, 1005 consecutive radically treated patients' charts were audited, 67 radiotherapy errors affecting 60 patients, including 42 incidents and 25 near-misses were identified. Transcriptional errors (29%) were the most common type. Most errors occurred at the time of treatment planning (59.7%), with "plan information transfer to the radiation oncology information system" being the most frequently affected sub-step of the radiotherapy process (47.8%). More errors were noted at cobalt units (52/67; 77.6%) than at linear accelerators. Trend analysis showed an increased number of radiotherapy incidents on Fridays and near-misses on Mondays. Trend for increased radiotherapy errors noted in the evening over other shifts. On severity grading, most of the errors (54/60; 90%) were clinically insignificant (grade I/II). Inadequacies and non-adherence towards standard operating procedures, poor documentation and lack of continuing education were the three most prominent causes. CONCLUSION: Preliminary data suggest a vulnerability of LMIC set-up to radiotherapy errors and emphasises the need for the development of longitudinal prospective processes, such as voluntary reporting and a continued education system, to ensure robust and comprehensive safe practises on par with centres in developed countries.

Locally advanced cervical cancer: A study of 5-year outcomes.

BACKGROUND: Cervical cancer is the second most common cancer among Indian women. This present retrospective study was conducted to report patient outcomes with locally advanced cervical cancer treated in the year 2010. MATERIALS AND METHODS: Case records of cervical cancer patients registered from January 1, 2010, to December 31, 2010 were retrieved. A total of 1200 patients were registered, of which 583 received either definitive or adjuvant radiotherapy (RT). Of these, 345 patients who received complete treatment at our hospital were included for outcome analysis. Descriptive statistics were used to summarize patient- and treatment-related variables, and Kaplan-Meier analysis was performed for survival analysis. RESULTS: The median age was 56 years (range: 33-90). Squamous carcinoma was the most common histology (91.4%) and the majority were FIGO Stage III (45.4%). Median follow-up of the cohort was 44 months (1-85 months). The 5-year disease-free survival (DFS) across stages was 50%. Most important predictor of DFS was FIGO staging (Stage II vs. Stage III: 62% vs. 45%) and use of concurrent chemoradiotherapy (CTRT) l (RT vs. CTRT: 32% vs. 57%, respectively). Patients aged >70 years had a significantly poor DFS at 5 years; however, did not have any effect on survival. Grade 3 or more late toxicity was seen in only 5% of the patients. CONCLUSION: Five-year DFS of 62% and 45% of Stage II and III patients treated under routine care represents comparable stage-matched results to the rest of the world, respectively.

Implementation of failure mode and effective analysis for high dose rate brachytherapy at Tata Memorial Hospital, Mumbai, India.

PURPOSE: To report our experience of failure mode and effective analysis for high dose rate brachytherapy of gynaecological cancer carried out in our hospital. MATERIALS AND METHODS: Failure mode and effective analysis process described in AAPM TG 100 was followed: a multidisciplinary team consisting of two physicians, physicists, dosimetrists, a medical resident, a nurse, and a secretary was formed. A weekly meeting was held for four months. A process tree was created based on the overview of the entire process, with the main branches as follows: procedure in the operating room, patient imaging, contouring, treatment planning, machine quality assurance and treatment delivery. Each team member assigned the risk probability numbers based on the predefined scoring system. For a particular failure mode, if the risk probability number assigned by one member differed from the other, the highest risk probability number was taken into consideration. RESULTS: The process tree consisted of 185 nodes, with risk probability numbers ranging from 1-220, with 77 possible failure modes. Four nodes were found with risk probability numbers greater than 200, which were considered for immediate process improvements. Twenty-four nodes were found to be with risk probability numbers ranging from 100 to 200. All 24 processes were considered for process improvement, out of which 12 were found effective and feasible, which includes failure nodes with high severity score at least 8. The processes with high-risk probability numbers (greater than 200) were reduced after the introduction of process improvements. For the other processes, standard procedures were modified. The common causes of failure, were found to be due to lack of attention, human error and work pressure. CONCLUSIONS: Failure mode and effective analysis is a useful tool that uses a systematic approach for quality management of a specific process.

Role of 3T multiparametric-MRI with BOLD hypoxia imaging for diagnosis and post therapy response evaluation of postoperative recurrent cervical cancers.

OBJECTIVES: To assess the diagnostic value of multiparametric-MRI (MPMRI) with hypoxia imaging as a functional marker for characterizing and detecting vaginal vault/local recurrence following primary surgery for cervical cancer. METHODS: With institutional review board approval and written informed consent 30 women (median age: 45 years) from October 2009 to March 2010 with previous operated carcinoma cervix and suspected clinical vaginal vault/local recurrence were examined with 3.0T-MRI. MRI imaging included conventional and MPMRI sequences [dynamic contrast enhanced (DCE), diffusion weighted (DW), 1H-MR spectroscopy (1HMRS), blood oxygen level dependent hypoxia imaging (BOLD)]. Two radiologists, blinded to pathologic findings, independently assessed the pretherapy MRI findings and then correlated it with histopathology findings. Sensitivity, specificity, positive predictive value, negative predictive value and their confidence intervals were calculated. The pre and post therapy conventional and MPMRI parameters were analyzed and correlated with response to therapy. RESULTS: Of the 30 patients, there were 24 recurrent tumors and 6 benign lesions. The accuracy of diagnosing recurrent vault lesions was highest at combined MPMRI and conventional MRI (100%) than at conventional-MRI (70%) or MPMRI (96.7%) alone. Significant correlation was seen between percentage tumor regression and pre-treatment parameters such as negative enhancement integral (NEI) (p = 0.02), the maximum slope (p = 0.04), mADC value (p = 0.001) and amount of hypoxic fraction on the pretherapy MRI (p = 0.01). CONCLUSION: Conventional-MR with MPMRI significantly increases the diagnostic accuracy for suspected vaginal vault/local recurrence. Post therapy serial MPMRI with hypoxia imaging follow-up objectively documents the response. MPMRI and BOLD hypoxia imaging provide information regarding tumor biology at the molecular, subcellular, cellular and tissue levels and this information may be used as an appropriate and reliable biologic target for radiation dose painting to optimize therapy in future.

Neoadjuvant Chemoradiation Followed by Surgery for Locally Advanced Gallbladder Cancers: A New Paradigm.

PURPOSE: Locally advanced (T3/T4) gallbladder cancers with large fixed portal nodes have a dismal prognosis. If undertaken, surgery entails extensive resections with high morbidity; therefore, in many centers, patients are offered palliative chemotherapy. In this prospective study, we used neoadjuvant concurrent chemoradiation with the intention of downstaging and facilitating R0 resection of these tumors. PATIENTS AND METHODS: Twenty-eight patients with locally advanced carcinoma gallbladder (stage III, having deep liver infiltrations and/or large portal nodes) underwent prior positron emission tomography/computed tomography to rule out metastatic disease. All were treated with concomitant chemoradiation using helical tomotherapy (dose of 57 Gy over 25 fractions to the gross tumor and 45 Gy over 25 fractions to the surrounding nodes) with injectable gemcitabine (300 mg/m(2)/week × 5 weeks). RESULTS: Of the 28 patients, 25 (89 %) successfully completed planned chemoradiation and 20 (71 %) achieved partial or complete radiologic response. Eighteen (64 %) patients were surgically explored, of whom 14 (56 %) achieved R0 resection. At the median follow-up of 37 months for the surviving patients, the median overall survival (OS) was 20 months for all patients. Only one patient recurred in the common bile duct postsurgery, whereas six patients had distant metastasis. The 5-year OS was 24 % for all patients and 47 % for patients with R0 resection. Biliary leak was seen in 6 (43 %) patients, of whom two required interventions. CONCLUSION: Locally advanced unresectable cancers may benefit from neoadjuvant chemoradiation to facilitate a curative resection with a good survival.

Vaginal displacement during course of adjuvant radiation for cervical cancer: results from a prospective IG-IMRT study.

OBJECTIVE: To compare internal target volume (ITV) generated using population-based displacements (ITV_study) with empty and full bladder scan fusion (ITV_EBFB) for organ-at-risk (OAR) doses during adjuvant intensity-modulated radiation therapy (IMRT) for cervical cancer. METHODS: From January 2011 to October 2012, patients undergoing IMRT were included. CT simulation was carried out after inserting vault markers. Planning target volume (PTV)_EBFB received 50 Gy per 25 fractions. Pre-treatment megavoltage CT (MVCT) was performed. MVCTs were registered using bony landmarks with Day 1 MVCT. Displacement of the centre of mass of markers was measured along each axis. Directional ITV was calculated using mean ± 2 standard deviations (SDs) (ITV_study). Replanning was performed using PTV study, and OAR doses were compared with PTV_EBFB using Wilcoxon test. RESULTS: A total of 348/386 data sets were evaluable for 16 patients. The median vaginal displacement was 1.2 mm (SD, 1.3 mm), 4.0 mm (SD, 3.5 mm) and 2.8 mm (SD, 3.3 mm) in the mediolateral, superoinferior and anteroposterior directions, respectively. The ITV margins were 4.1, 10.3 and 10.6 mm. ITV_study and ITV_EBFB were 115.2 cm(3) (87.7-152.2 cm(3)) and 151 cm(3) (95.7-277.1 cm(3)) (p < 0.0001), respectively. PTV_study and PTV_EBFB were 814 and 881 cm(3) (p < 0.0001), respectively. Median doses to the bladder were lower with the PTV_study (46.2 Gy vs 43.2 Gy; p = 0.0001), and a similar trend was observed in the volume of the small bowel receiving 40 Gy (68.2 vs 60.1 cm(3); p = 0.09). CONCLUSION: Population-based PTV margins can lead to reduction in OAR doses. ADVANCES IN KNOWLEDGE: Population-based ITV may reduce OAR doses while executing adjuvant IMRT for cervical cancer.

Investigation on the effect of sharp phantom edges on point dose measurement during patient-specific dosimetry with Rapid Arc.

The objective of this work was to investigate and quantify the effect of sharp edges of the phantom on the point dose measurement during patient-specific dosimetry with Rapid Arc (RA). Ten patients with carcinoma of prostate were randomly selected for this dosimetric study. Rapid Arc plans were generated with 6 MV X-rays in the Eclipse (v 8.6.14) with single arc (clockwise). Dosimetry verification plans were generated for two phantoms (cylindrical and rectangular). The cylindrical phantom was solid water (diameter 34 cm) and the rectangular phantom was a water phantom (25 cm × 25 cm × 10 cm). These phantoms were pre-scanned in computed tomography (CT) machine with cylindrical ionization chamber (FC65) in place. The plans were delivered with Novalis Tx linear accelerator with 6 MV X-rays for both the phantoms separately. The measured dose was compared with the planned dose for both the phantoms. Mean percentage deviation between measured and planned doses was found to be 4.19 (SD 0.82) and 3.63 (SD 0.89) for cylindrical and rectangular phantoms, respectively. No significant dosimetric variation was found due to the geometry (sharp edges) of the phantom. The sharp edges of the phantom do not perturb the patient specific Rapid Arc dosimetry significantly.

Synthesis, characterization and antiproliferative activity of 1,2-naphthoquinone and its derivatives.

In the present study substituted 1,2-naphthoquinones were synthesized, purified and characterized by spectroscopic studies (UV, FT-IR, ¹H NMR, ¹³ C NMR and elemental analysis). These compounds were evaluated for cytotoxicity against a panel of human cancer cell lines (Hep-G2 for liver sarcoma, MG-63 for osteosarcoma and MCF-7 for human breast cancer). The cells were dosed with these ortho-naphthoquinone derivatives at varying concentrations, and cell viability was measured by a 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay with doxorubicin as positive control. Significant anticancer activities were observed in vitro for some members of the series, and compounds 1,2-naphthoquinone 2-thiosemicarbazone, 1,2-naphthoquinone-2-semicarbazone, 4-amino-1,2-naphthoquinone 2-thiosemicarbazone and 4-amino-1,2-naphthoquinone-2-semicarbazone are active cytotoxic agents against different cancer cell lines with IC50 values in the range of 5.73-17.67 µM. The obtained data suggested that better anticancer activity was linked with introduction of thiosemicarbazone and semicarbazone moiety in 1,2-naphthoquinone ring system. Outcomes of experimentation also reveal that incorporation of amino group in 1,2-naphthoquinone moiety contributes positively for cytotoxic action of compounds. Docking experiments showed a good correlation between their calculated interaction energies with the topoisomerase-II and the observed IC50 values of all these compounds.

Does helical tomotherapy improve dose conformity and normal tissue sparing compared to conventional IMRT? A dosimetric comparison in high risk prostate cancer.

The study was designed to compare Helical Tomotherapy (HT) based IMRT and conventional sliding window (SW IMRT) in patients with high risk prostate cancer. Complementary plans with HT and SWIMRT were compared using DVH parameters. The PTV Prostate was prescribed 74 Gy in 37 fractions and the nodal PTV received 55 Gy in 37 fractions by simultaneous integrated boost. Conformity Index, Homogeneity Index and dose-volume parameters were compared. The conformity index (CI) of HT (0.77, SD = 0.54) plans tended to be better (p = 0.069) compared to SWIMRT (0.70, SD = 0.01) for prostate PTV. CI for nodal PTV was similar. Helical tomotherapy plans were more homogeneous, with homogeneity index (HI) of 0.04 compared to 0.06 in SWIMRT (p = 0.018) for PTV prostate and HI of 0.06 and 0.15 (p = 0.025) for PTV nodes respectively. Median dose to bladder (p = 0.025) and rectum (p = 0.012) were less with HT. However, HT delivered a higher D10Gy and D1Gy to rectum and bladder overlap volumes as a consequence of achieving better homogeneity. Femoral heads were better spared with HT plans (p = 0.012). HT improves dose homogeneity, target coverage and conformity as compared to SWIMRT, with overall improvement in critical organ sparing.

From two-dimensional to three-dimensional conformal radiotherapy in prostate cancer: an Indian experience.

BACKGROUND: Sparse data from India are available regarding the outcome of prostate cancer treatment. We report our experience in treating prostate cancer with radiotherapy (RT). MATERIALS AND METHODS: This study included 159 men with locally advanced cancer treated with RT with or without hormone therapy between 1984 and 2004. The median RT dose was 70 Gy over 35 fractions. Eighty-five patients received whole pelvic RT and prostate boost, and 74 patients were treated with 3-dimensional conformal radiotherapy (3DCRT) to prostate and seminal vesicles alone. RESULTS: The median follow-up was 25 months and the freedom from biochemical failure for all the patients at 5 years was 76%, disease-free survival (DFS) 59.1%, and overall survival (OAS) was 70.1%. The risk stratification (91% vs 52%, P < 0.03) and RT dose (72.8% for dose > 66 Gy vs 43.5% for dose < 66 Gy; P = 0.01) affected the DFS. DFS at 5 years was better in the group receiving 3DCRT to prostate and seminal vesicles (78% vs 51.5%; P = 0.001) and was reflected in OAS as well (P = 0.01). CONCLUSION: CRT technique with dose escalation results in significant benefit in DFS and OAS in locally advanced prostate cancer.

Non-Hodgkin's lymphoma of Waldeyer's ring in children: outcome using chemotherapy and involved field radiotherapy.

AIM: To evaluate the prognostic factors and treatment outcome of children with non-Hodgkin's lymphoma (NHL) of Waldeyer's ring treated at a single institution. MATERIALS AND METHODS: Thirty-two children with NHL of Waldeyer's ring treated at our institute between January 1990 and December 2001 were included in this analysis. The median age at presentation was 14 years, and most of the patients (87%) were boys. The most common histological subtype was diffuse large B-cell lymphoma (75%), 25% patients had stage I and 75% had stage II disease. Treatment comprised a combination of chemotherapy and radiotherapy in most of the patients (75%). Among these patients, 71% received a radiotherapy dose of > or = 45 Gy. RESULTS: After a median follow-up of 45 months, the 5-year disease-free and overall survival rates were 76.5 and 83.2%, respectively. Age > 10 years (P = 0.032), bulky tumours (P = 0.001) and the presence of B-symptoms (P = 0.004) had a negative influence on disease-free survival. Patients treated with a combination of chemotherapy and radiotherapy had a better outcome than patients treated with chemotherapy alone (disease-free survival: 87.1% vs 56.2%, P = 0.056). The complete response (P = 0.003), disease-free survival (P = 0.001) and overall survival (P = 0.001) rates were significantly better for patients receiving a radiotherapy dose > or = 45 Gy. CONCLUSION: The age at diagnosis, the size of the tumour, and the presence of B-symptoms significantly influenced the outcome of children with NHL of Waldeyer's ring in this study. A combined modality treatment, comprising chemotherapy and radiotherapy, resulted in a satisfactory outcome in patients with this rare neoplasm.

Case report: Second primary small cell carcinoma of the trachea in a breast cancer survivor: a case report and literature review.

Small cell carcinoma of the trachea is a rare entity and only a few cases have been described, none as a second malignant neoplasm. This is the first report of a metachronous second primary of the trachea with small cell histology in a breast cancer survivor. A 25-year-old woman was diagnosed initially with an infiltrating ductal carcinoma of the breast, and was treated with modified radical mastectomy followed by adjuvant chemo-radiotherapy. 10 years later, she presented with breathlessness and central airway obstruction. Bronchoscopy revealed an intraluminal lesion in the proximal trachea, which was reported as small cell carcinoma on biopsy. There was no evidence of loco-regional recurrence of the previously treated breast cancer. Whole-body positron emission tomography did not show any distant metastases. As it was a small cell carcinoma, she was treated with concurrent chemo-radiotherapy and remains loco-regionally controlled. Decision-making in such instances should take into account prior treatment and needs to be individualized. There is a need for increased awareness amongst primary care physicians regarding second malignant neoplasms in the long-term follow-up of breast cancer patients treated with radiation and chemotherapeutic agents that have carcinogenic potential.
