Internal mammary and medial supraclavicular lymph node chain irradiation in stage I-III breast cancer (EORTC 22922/10925): 15-year results of a randomised, phase 3 trial.

BACKGROUND: 10-year results from several studies showed improved disease-free survival and distant metastasis-free survival, reduced breast cancer-related mortality, and variable effects on overall survival with the addition of partial or comprehensive regional lymph node irradiation after surgery in patients with breast cancer. We present the scheduled 15-year analysis of the European Organisation for Research and Treatment of Cancer (EORTC) 22922/10925 trial, which aims to investigate the impact on overall survival of elective internal mammary and medial supraclavicular (IM-MS) irradiation. METHODS: EORTC 22922/10925, a randomised, phase 3 trial done across 46 radiation oncology departments from 13 countries, included women up to 75 years of age with unilateral, histologically confirmed, stage I-III breast adenocarcinoma with involved axillary nodes or a central or medially located primary tumour. Surgery consisted of mastectomy or breast-conserving surgery and axillary staging. Patients were randomly assigned (1:1) centrally using minimisation to receive IM-MS irradiation at 50 Gy in 25 fractions (IM-MS irradiation group) or no IM-MS irradiation (control group). Stratification was done for institution, menopausal status, site of the primary tumour within the breast, type of breast and axillary surgery, and pathological T and N stage. Patients and investigators were not masked to treatment allocation. The primary endpoint was overall survival analysed according to the intention-to-treat principle. Secondary endpoints were disease-free survival, distant metastasis-free survival, breast cancer mortality, any breast cancer recurrence, and cause of death. Follow-up is ongoing for 20 years after randomisation. This study is registered with ClinicalTrials.gov, NCT00002851. FINDINGS: Between Aug 5, 1996, and Jan 13, 2004, we enrolled 4004 patients, of whom 2002 were randomly assigned to the IM-MS irradiation group and 2002 to the no IM-MS irradiation group. At a median follow-up of 15·7 years (IQR 14·0-17·6), 554 (27·7%) patients in the IM-MS irradiation group and 569 (28·4%) patients in the control group had died. Overall survival was 73·1% (95% CI 71·0-75·2) in the IM-MS irradiation group and 70·9% (68·6-72·9) in the control group (HR 0·95 [95% CI 0·84-1·06], p=0·36). Any breast cancer recurrence (24·5% [95% CI 22·5-26·6] vs 27·1% [25·1-29·2]; HR 0·87 [95% CI 0·77-0·98], p=0·024) and breast cancer mortality (16·0% [14·3-17·7] vs 19·8% [18·0-21·7]; 0·81 [0·70-0·94], p=0·0055) were lower in the IM-MS irradiation group than in the control group. No significant differences in the IM-MS irradiation group versus the control group were seen for disease-free survival (60·8% [95% CI 58·4-63·2] vs 59·9% [57·5-62·2]; HR 0·93 [95% CI 0·84-1·03], p=0·18), or distant metastasis-free survival (70·0% [67·7-72·2] vs 68·2% [65·9-70·3]; 0·93 [0·83-1·04], p=0·18). Causes of death between groups were similar. INTERPRETATION: The 15-year results show a significant reduction of breast cancer mortality and any breast cancer recurrence by IM-MS irradiation in stage I-III breast cancer. However, this is not converted to improved overall survival. FUNDING: US National Cancer Institute, Ligue Nationale contre le Cancer, and KWF Kankerbestrijding.

Modification of initial therapy in early and advanced Hodgkin lymphoma, based on interim PET/CT is beneficial: a prospective multicentre trial of 355 patients.

This multicentre study evaluated 5-year progression-free (PFS) and overall survival (OS) in early and advanced Hodgkin lymphoma (HL), where therapy was individualized based on initial prognostic factors and positron emission tomography-computed tomography performed after two cycles (PET-2). Between September 2006 and August 2013, 359 patients aged 18-60 years, were recruited in nine Israeli centres. Early-HL patients initially received ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) ×2. Depending on initial unfavourable prognostic features, PET-2-positive patients received additional ABVD followed by involved-site radiotherapy (ISRT). Patients with negative PET-2 and favourable disease received ISRT or ABVD ×2; those with unfavourable disease received ABVD ×2 with ISRT or, alternatively, ABVD ×4. Advanced-HL patients initially received ABVD ×2 or escalated BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, prednisone; EB) ×2 based on their international prognostic score (≤2 or ≥3). PET-2-negative patients further received ABVD ×4; PET-2-positive patients received EB ×4 and ISRT to residual masses. With a median follow-up of 55 (13-119) months, 5-year PFS was 91% and 69% for PET-2-negative and positive early-HL, respectively; 5-year OS was 100% and 95%, respectively. For advanced-HL, the PFS was 81% and 68%, respectively (P = 0·08); 5-year OS was 98% and 91%, respectively. PET-2 positivity is associated with inferior prognosis in early-HL, even with additional ABVD and ISRT. Advanced-HL patients benefit from therapy escalation following positive PET-2. EB can be safely de-escalated to ABVD in PET-2-negative patients.

Tolerance of the vaginal vault to high-dose rate brachytherapy and concomitant chemo-pelvic irradiation: Long-term perspective.

AIM/BACKGROUND: We sought to determine the tolerance level and complication rates of the vaginal vault to combined high-dose-rate intra-cavitary brachytherapy with concomitant chemo-radiotherapy. PATIENTS AND METHODS: A retrospective review of medical records of all the patients who received definitive chemo-radiotherapy for cervical cancer between 1998 and 2002 was undertaken. The records were reviewed for doses and for radiation-associated early and late sequelae of the vagina, rectum and bladder. Cumulative biological effective dose was calculated for two reference vaginal surface points. RESULTS: Fifty patients were included. Average age at diagnosis was 54 years. Median follow-up was 59 months. There were no recorded instances of acute grade IV toxicity. Maximal high-dose-rate vaginal surface dose (upper central point) was 103 Gy, and maximal brachytherapy lateral surface dose was 70 Gy. Maximal cumulative biological effective dose for the lateral surface reference point was 465.5 Gy3, and the maximal cumulative biological effective dose for the superior reference point was 878.6 Gy3. There were no cases of vaginal necrosis or fistulas, and no cases of grade IV late vaginal, rectal or bladder toxicity. No correlation was found between the maximal vaginal surface dose and vaginal, rectal or bladder toxicity. CONCLUSIONS: The maximal surface HDR brachytherapy dose of 103 Gy and the maximal cBED of 878.6 Gy3 were not associated with fistula or necrosis or other grade 3-4 vaginal complications. Concomitant chemo-radiotherapy, including pelvic radiotherapy and high-dose-rate intracavitary brachytherapy, is relatively safe for cervical cancer patients.

Mapping the location of local and regional recurrences according to breast cancer surgery and radiation therapy: Results from EORTC 22922/10925.

The purpose of this study is to evaluate the influence of the extent of surgery and radiation therapy (RT) on the rates and sites of local (LR) and regional recurrences (RR) in the EORTC 22922/10925 trial. PATIENTS AND METHODS: All data were extracted from the trial's individual patients' case report forms (CRF) and analysed with a median follow-up of 15.7 years. Cumulative incidence curves were produced for LR and RR accounting for competing risks: an exploratory analysis of the effect of the extent of surgical and radiation treatments on LR rate was conducted using the Fine & Gray model accounting for competing risks and adjusted for baseline patient and disease characteristics. The significance level was set at 5%, 2-sided. Frequency tables were used to describe the spatial location of LR and RR. RESULTS: Out of 4004 patients included in the trial, 282 (7%) patients experienced LR and 165 (4.1%) RR, respectively. Cumulative incidence rate of LR at 15 years was lower after mastectomy (3.1%) compared to BCS + RT (7.3%) (F&G: HR (Hazard Ratio) = 0.421, 95%CI = 0.282-0.628, p-value < 0.0001). LR were similar up to 3 years for both mastectomy and BCS but continued to occur at a steady rate for BCS + RT, only. The spatial location of the recurrence was related to the locoregional therapy applied and the absolute gain of RT correlated to stage of disease and extent of surgery. CONCLUSIONS: The extent of locoregional therapies impacts significantly on LR and RR rates and spatial location.

Breast-conserving surgery and intraoperative electron radiotherapy in early breast cancer: experience at the Rambam Health Care Campus.

BACKGROUND: Local recurrences after breast-conserving surgery occur mostly at the site of the primary carcinoma. The main objective of postoperative radiotherapy is sterilization of residual cancer cells. Whole-breast radiotherapy is the standard of care, but its utility has recently been challenged in favor of radiotherapy limited to the area at highest risk of recurrence. Intraoperative electron radiotherapy (IOeRT) is an innovative technique for accelerated partial breast irradiation (APBI) that is applied to selected patients affected by early breast cancer. OBJECTIVES: To describe our experience with IOeRT at the Rambam Health Care Campus in Haifa since we began utilizing this modality in 2006. METHODS: From April 2006 to September 2010, 31 patients affected by unifocal invasive duct breast carcinoma < or = 2 cm diameter received wide local resection followed by intraoperative radiotherapy with electrons. Patients were evaluated for early and late complications, and other events, 1 month after surgery and every 3 months thereafter for the duration of the first 2 years. RESULTS: After a mean follow-up of 36 months, seven patients developed mild breast fibrosis and three suffered from mild postoperative infection. Rib fractures were observed in four patients before routine lead shielding was initiated. Additional whole-breast irradiation was given to four patients. None of the patients developed local recurrences or other ipsilateral cancers. Similarly, no contralateral cancers or distant metastases were observed. CONCLUSIONS: Intraoperative electron radiotherapy may be an alternative to external beam radiation therapy in an appropriate selected group of early-stage breast cancer patients. However, long-term results of clinical trials are required to better evaluate the indications and utility of this technique in the management of breast cancer.

[F18]FDG PET/CT-Derived Metabolic and Volumetric Biomarkers Can Predict Response to Treatment in Locally Advanced Cervical Cancer Patients.

(1) Purpose: Current study aimed at evaluating the relationship between quantitative metabolic and volumetric FDG PET/CT parameters and the response to definitive chemoradiation therapy in locally advanced cervical cancer patients; (2) Methods: Ninety newly diagnosed locally advanced cervical cancer patients (FIGO IB2-IVA) were investigated. All patients underwent PET/CT at staging and after treatment. Metabolic and volumetric parameters, including SUVmax, SUVmean, Total Lesion Glycolysis (TLG), and Metabolic Tumor Volume (MTV) of the primary tumor and metastatic lymph nodes were measured and compared between patients with and without complete metabolic response (CMR). A similar analysis was performed in a subgroup of FIGO IB2-IIB patients; (3) Results: SUVmax and SUVmean of the primary tumor as well as those of metastatic lymph nodes, MTV, and TLG were found to be significantly different between CMR and non-CMR patients. In a subgroup of patients with FIGO IB2-IIB disease, MTV and TLG identified women who will achieve CMR with a threshold of 31.1 cm3 for MTV and 217.8 for TLG; (4) Conclusions: PET/CT-derived quantitative metabolic and volumetric parameters are higher in locally advanced cervical cancer patients who will not respond to definitive chemoradiation therapy. Specifically, in patients who are not metastatic at staging, MTV and TLG values can serve as a predictor for treatment response and thus may alter treatment strategy.

Classification of breast cancer precursors through exhaled breath.

Certain benign breast diseases are considered to be precursors of invasive breast cancer. Currently available techniques for diagnosing benign breast conditions lack accuracy. The purpose of this study was to deliver a proof-of-concept for a novel method that is based on breath testing to identify breast cancer precursors. Within this context, the authors explored the possibility of using exhaled alveolar breath to identify and distinguish between benign breast conditions, malignant lesions, and healthy states, using a small-scale, case-controlled, cross-sectional clinical trial. Breath samples were collected from 36 volunteers and were analyzed using a tailor-made nanoscale artificial NOSE (NA-NOSE). The NA-NOSE signals were analyzed using two independent methods: (i) principal component analysis, ANOVA and Student's t-test and (ii) support vector machine analysis to detect statistically significant differences between the sub-populations. The NA-NOSE could distinguish between all studied test populations. Breath testing with a NA-NOSE holds future potential as a cost-effective, fast, and reliable diagnostic test for breast cancer risk factors and precursors, with possible future potential as screening method.

The impact of radiation therapy on vaginal biomechanical properties.

OBJECTIVE: In women with cervical cancer (CC), treatment with radiation causes changes in vaginal biomechanical properties, anatomy and function. The aims of the current study were to objectively assess effects of radiotherapy (RT) on vaginal elasticity, wall mobility and contraction strength; and to evaluate associations of these changes with sexual function. STUDY DESIGN: This prospective cohort study was approved by our Institutional Review Board. Between May 2018 and June 2020, women with CC who were candidates for RT were eligible to participate. Participants underwent vaginal tactile imaging (VTI) evaluation and were asked to fill the Female Sexual Function Index (FSFI) questionnaire at the time of first RT session and at a 6-month post-treatment follow up visit. Women who underwent radical hysterectomy, or had pelvic side-wall, pelvic or distant organ metastasis were not included. RESULTS: A total of 25 women with locally advanced CC were included in the final analysis. The mean age was 39 ± 2.7 years, the mean BMI was 24.8 ± 2.2 kg/m2 and the median parity was 2 (range: 1-5). Following RT, the mean scores for vaginal elasticity and vaginal tightening were significantly lower than at pre-treatment: 11.3 ± 2.5 vs. 28.3 ± 9, P < 0.0001 and 2.6 ± 0.7 vs. 16.7 ± 3, P < 0.0001, respectively. Following RT, significant decreases were demonstrated in vaginal wall mobility and pelvic muscle contraction strength: from 1.77 ± 0.34 to 0.36 ± 0.15, P < 0.0001 and from 2.55 ± 0.48 to 0.52 ± 0.23, P < 0.0001, respectively. Compared to pre-treatment, post-RT vaginal length was significantly shorter (3.30 ± 0.22 vs. 7.64 ± 0.63, P = 0.0023) and sexual intercourse frequency significantly lower: 1 (range 1-2) vs. 2 (range 1-4), P = 0.014). The mean total FSFI score was significantly lower following RT (6.7 ± 1 vs. 14.5 ± 2.7, P < 0.0001). CONCLUSIONS: Women with locally advanced CC who have been treated with RT exhibit persistent vaginal biomechanical changes that compromise sexual activity and result in considerable distress.

Outcome after combined modality treatment for uterine papillary serous carcinoma: a study by the Rare Cancer Network (RCN).

OBJECTIVES: Uterine papillary serous carcinoma (UPSC) is a rare subtype of endometrial carcinoma, characterized by a poor outcome. We sought to better analyze the effect of surgery and adjuvant therapies on this disease. METHODS: A retrospective analysis was performed on the records of 138 women diagnosed with UPSC between 1986 and 2003 in the framework of the Rare Cancer Network. RESULTS: Median age at diagnosis was 67 years. Pure UPSC was found in 107 patients and mixed histology in 30. Fifty-four patients had stage I, 20 stage II, 41 stage III and 23 stage IV disease. Median follow-up for the surviving patients was 44 months. Surgery was performed in 129 patients, after which 122 were rendered free of gross disease and comprised the adjuvant group. Of these, 23 received platinum-based chemotherapy. Radiotherapy was applied in 52 patients and 28 underwent combined chemo-radiotherapy. At last follow-up, 57 patients were alive free of disease, 10 were alive with disease, 62 died of disease, 8 died of other causes and 1 died due to toxicity. Five-year disease-free survival (DFS), disease-specific survival (DSS) and overall survival for the 122 patients treated with curative intent were 42%, 56% and 54%, respectively. In multivariate analysis, age, stage, histology and adjuvant chemotherapy were significant for DFS; age, stage and histology were significant for DSS. Radiotherapy reduced the pelvic recurrence rate from 29% to 14% (p=0.047). CONCLUSIONS: UPSC harbours a moderate prognosis, with age, stage and histology as significant prognosticators. Conservative surgery followed by adjuvant chemotherapy and pelvic radiotherapy can be suggested as an appropriate treatment approach for patients treated with curative intent.

Long-term outcomes in patients with nasopharyngeal carcinoma treated with reduced-volume conformal radiotherapy: A retrospective cohort study.

INTRODUCTION: While the optimal target volumes for primary nasopharyngeal tumour are still subject to debate, we evaluated primary tumour volumes in nasopharyngeal carcinoma (NPC) patients treated according to an institutional protocol with a reduced volume approach and compared them to those determined by Radiation Therapy Oncology Group (RTOG)-0615 guidelines. METHODS: This single-centre retrospective analysis included 36 NPC patients treated between 2/2007 and 3/2014. Planning target volume (PTV)-P 50 (50 Gy isodose to the primary tumour) included the gross tumour and the entire nasopharyngeal mucosa (clinical target volume [CTV]-P 50) with 5 mm margins. The PTV-P 50 volumes, as determined by our protocol, were compared to those obtained with RTOG-0615 PTV-P 59.4 (59.4 Gy to the primary tumour). Clinical outcomes were also analysed. RESULTS: Median (range) follow-up: 48 (21-108) months; 88.9% were males; median age was 53 (27-86) years; 14%, 53%, and 33% had stage II, III, and IV disease at diagnosis, respectively. Median volume of PTV-P 50: 209.0 (92.6-568.0) cc. Median volume of RTOG-0615 PTV-P 59.4-P: 292.0 (123.6-425.1) cc. The PTV-P volume was significantly smaller than that delineated according to the RTOG-0615 protocol (p < 0.001). Isolated local relapse as first site of recurrence occurred in five patients: two with stage III, two with IVA and one with IVB disease; all had advanced local disease at diagnosis. All local recurrences occurred in the PTV-P 69-70 region. CONCLUSION: A reduced volume approach for radiotherapy in primary NPC provided acceptable long-term local control.

[Gynecomastia as a complication of hormonotherapy for prostate cancer: effect of prophylactic breast irradiation].

Gynecomastia is a benign condition characterized by proliferation of mammary glandular tissue. Hormonotherapy with bicalutamide for prostate cancer is one of the causes of gynecomastia. The well known aim of treatment is to decrease psychological distress and to improve cosmetic appearance. Prophylactic breast irradiation may prevent the appearance of gynecomastia.

Outcome and Predictive Factors in Uterine Carcinosarcoma Using Postoperative Radiotherapy: A Rare Cancer Network Study.

Uterine carcinosarcomas (UCS) are rare tumors. Consensus regarding therapeutic management in non-metastatic disease is lacking. This study reports on outcome and predictive factors when using postoperative radiotherapy. We analyzed a retrospective analysis in 124 women treated between 1987-2007 in the framework of the Rare-Cancer-Network. Median follow-up was 27 months. Postoperative pelvic EBRT was administered in 105 women (85%) and 92 patients (74%) received exclusive or additional vaginal brachytherapy. Five-year overall survival (OS), disease-free survival (DFS), cancer specific survival (CSS) and locoregional control (LRC) were 51.6% (95% CI 35-73%), 53.7% (39-71%), 58.6% (38-74%) and 48% (38-67%). Multivariate analysis showed that external beam radiation therapy (EBRT) >50Gy was an independent prognostic factor for better OS (P=0.03), CSS (P=0.02) and LRC (P=0.01). Relative risks (RR) for better OS (P=0.02), DFS (P=0.04) and LRC (P=0.01) were significantly associated with younger age (≤60 years). Higher brachytherapy (BT)-dose (>9Gy) improved DFS (P=0.04) and LRC (P=0.008). We concluded that UCS has high systemic failure rate. Local relapse was reduced by a relative risk factor of over three in all stages of diseases when using higher doses for EBRT and brachytherapy. Postoperative RT was most effective in UCS stage I/II-diseases.

Response of adenocarcinoma of the uterine cervix to chemoradiotherapy.

The aim of the current retrospective study was to investigate the response of advanced cervical adenocarcinoma (AC) to definitive chemoradiotherapy. Uterine cervical cancer is one of the most common cancer types among females, with squamous cell carcinoma (SQCC) being the most prevalent histological type. The incidence of cervical AC and its variants has markedly increased in recent decades. The current understanding with regard to the treatment of cervical cancer has been established through studies in which the majority of the patients suffered from SQCC, while only a limited number of studies have focused on the treatment of AC. Therefore, the optimal treatment for uterine cervical AC remains unclear. In the present study, data were collected from the medical files of patients who were diagnosed with advanced uterine cervical AC and treated with chemoradiotherapy between 1998 and 2013. Data were also collected from a group of patients with SQCC for comparison with AC patients in terms of response and survival. A total of 68 uterine cervical cancer cases were included, including 29 AC patients and 39 SQCC patients. Compared with the SQCC subgroup, a higher number of AC patients required surgery following chemoradiotherapy due to a lack of response to the initial treatment (5% vs. 31%, respectively; P=0.0065). After a median follow-up period of 10 years, patients with AC exhibited shorter overall survival (7.4 years vs. 11 years for AC and SQCC groups, respectively; P=0.01). Differences in recurrence (40.7% vs. 34.4%; P=0.79) and disease-free interval (1.2 years vs. 2 years; P=0.11) were not statistically significant. The results indicated that cervical AC is less responsive to chemoradiotherapy compared with SQCC.

Outcome and prognostic factors in endometrial stromal tumors: a Rare Cancer Network study.

PURPOSE: To provide further understanding regarding outcome and prognostic factors of endometrial stromal tumors (EST). METHODS AND MATERIALS: A retrospective analysis was performed on the records of 59 women diagnosed with EST and treated with curative intent between 1983 and 2007 in the framework of the Rare Cancer Network. RESULTS: Endometrial stromal sarcomas (ESS) were found in 44% and undifferentiated ESS (UES) in 49% of the cases. In 7% the grading was unclear. Of the total number of patients, 33 had Stage I, 4 Stage II, 20 Stage III, and 1 presented with Stage IVB disease. Adjuvant chemotherapy was administered to 12 patients, all with UES. External-beam radiotherapy (RT) was administered postoperatively to 48 women. The median follow-up was 41.4 months. The 5-year overall survival (OS) rate was 96.2% and 64.8% for ESS and UES, respectively, with a corresponding 5-year disease-free survival (DFS) rate of 49.4% and 43.4%, respectively. On multivariate analysis, adjuvant RT was an independent prognostic factor for OS (p = 0.007) and DFS (p = 0.013). Locoregional control, DFS, and OS were significantly associated with age (≤60 vs. >60 years), grade (ESS vs. UES), and International Federation of Gynecology and Obstetrics stage (I-II vs. III-IV). Positive lymph node staging had an impact on OS (p < 0.001). CONCLUSION: The prognosis of ESS differed from that of UES. Endometrial stromal sarcomas had an excellent 5-year OS, whereas the OS in UES was rather low. However, half of ESS patients had a relapse. For this reason, adjuvant treatment such as RT should be considered even in low-grade tumors. Multicenter randomized studies are still warranted to establish clear guidelines.

Cytokines levels, severity of acute mucositis and the need of PEG tube installation during chemo-radiation for head and neck cancer--a prospective pilot study.

BACKGROUND: The purpose of this pilot study was to detect a correlation between serum cytokine levels and severity of mucositis, necessitating installation of a percutaneous endoscopic gastrostomy tube (PEG) in head and neck (H&N) cancer patients receiving combined chemo-radiation therapy. PATIENTS AND METHODS: Fifteen patients with H&N epithelial cancer were recruited to this study. All patients received radiotherapy to the H&N region, with doses ranging from 50-70 Gy. Chemotherapy with cisplatin, carboplatin, 5-fluorouracil and taxanes was given to high-risk patients, using standard chemotherapy protocols. Patients were evaluated for mucositis according to WHO common toxicity criteria, and blood samples were drawn for inflammatory (IL-1, IL-6, IL-8, TNF-alpha) and anti-inflammatory (IL-10) cytokine levels before and during treatment. RESULTS: A positive correlation was found between IL-6 serum levels and severity of mucositis and dysphagia; specifically, high IL-6 levels at week 2 were correlated with a need for PEG tube installation. A seemingly contradictory correlation was found between low IL-8 serum levels and a need for a PEG tube. CONCLUSION: These preliminary results, indicating a correlation between IL-6 and IL-8 serum levels and severity of mucositis and a need for a PEG tube installation, justify a large scale study.

Diagnosing lung cancer in exhaled breath using gold nanoparticles.

Conventional diagnostic methods for lung cancer are unsuitable for widespread screening because they are expensive and occasionally miss tumours. Gas chromatography/mass spectrometry studies have shown that several volatile organic compounds, which normally appear at levels of 1-20 ppb in healthy human breath, are elevated to levels between 10 and 100 ppb in lung cancer patients. Here we show that an array of sensors based on gold nanoparticles can rapidly distinguish the breath of lung cancer patients from the breath of healthy individuals in an atmosphere of high humidity. In combination with solid-phase microextraction, gas chromatography/mass spectrometry was used to identify 42 volatile organic compounds that represent lung cancer biomarkers. Four of these were used to train and optimize the sensors, demonstrating good agreement between patient and simulated breath samples. Our results show that sensors based on gold nanoparticles could form the basis of an inexpensive and non-invasive diagnostic tool for lung cancer.
