the 5-year LRR, DDR, DFS and OS were respectively: 3.4%,

13.2%, 84.5% and 92.1%. In the PMRT group, the 5-year

LRR, DDR, DFS and OS were 4.5%, 14.1%, 85.9%, and 94.7%,

respectively. In the non-PMRT group, the 5-year LRR, DDR,

DFS and OS were 2.4%, 12.4%, 84.2% and 92.3%,

respectively. In these small single center series, there was

no difference in LRR, DDR, DFS and OS between the PMRT

and non-PMRT group. There was no significant impact of

comorbidity, T-stage, number of positive nodes, HR

status, HER2 status and adjuvant chemotherapy on the

effect of PMRT.

Conclusion

The benefit of PMRT might be limited in the unselected

elderly patients with T1-2 and 1 to 3 positive nodes. The

intensity of anti-cancer treatment including adjuvant

chemotherapy and PMRT tends to decrease in patients

with increased age at diagnosis. Larger study is needed to

identify elderly patients with relative higher risk of LRR

and metastasis, as well as the risk of toxicity to better

individualize treatment. Clear biomarkers are needed to

decide patients for whom radiotherapy can be avoided.

Purpose or Objective

Elderly patients have been underrepresented in

prospective clinical trials that have defined standards of

care for head and neck cancer. In the era of improved

radiation techniques, improved systemic therapy and

better supportive care can claim that chemoradiation

does, in fact, improve survival for a large segment of this

population and should not be denied for fear of poor

tolerance.

Material and Methods

21 patients with locally advanced head and neck cancer

treated with SIB-IMRT and concurrent weekly cisplatin

were prospectively evaluated. After written and informed

consent, all patients were immobilised with head and neck

thermoplastic mask followed by CT simulation. Critical

structures and Planning Target volumes – high risk

receiving 70Gy (PTVHR), intermediate risk receiving 63 or

59.4 Gy (PTVIR) and low risk receiving 56 or 54Gy (PTVLR)

in 33-35 fractions over 6.5-7 weeks were defined and

planned with Eclipse version 11 planning system using 7-9

field arrangements. Concurrent Chemotherapy was

administered using weekly cisplatin 40mg/m2 or

carboplatin AUC 2 for 6 cycles. All patients were evaluated

for treatment compliance and radiation toxicities weekly.

Outcomes were analysed in terms of clinical response

evaluation using RECIST criteria, acute toxicities

according to RTOG-EORTC and overall survival using

Kaplan Meir curve.

Results

Median age of presentation was 69 years (range 65-76)

with M: F ratio of 16:5. Primary site of presentation were

hypopharynx (10), oropharynx (5) and larynx (6). TNM

stage status were T1(2),T2(5), T3(11), T4(3); N1(4), N2(1),

N3(1); Stage III(10), IVA(10) and IVB(1). All patients

received 70 Gy. Median Overall treatment time was 53

days (range 46-65 days) with treatment interruption of 1-

9 days (median 3 days). All patients received 4-6 cycles of

cisplatin/carboplatin (median 6). Acute toxicities are

shown in table. Mean weight loss was 8% (range 4-

15%).With a median follow up of 9 months (range 3-15

months), ORR were 71.5% (15 patients) had complete

response and 28.5% (6 patients) had partial response. 7

(33%) patients had recurrence with 6 loco regional and 1

distant, out of which 3 expired and 4 are alive with

disease. The overall 15 month survival rate is 75.6%.

Conclusion

outcomes even in the subset of elderly patients with

locally advanced disease.

Purpose or Objective

Quality of life (QoL) is an important factor in patient care.

In this analysis we focused on QoL before and after radio-

(chemo-)therapy (RCT) in patients with thoracic

carcinomas and its influence on clinical follow up, survival

and the correlation with treatment related toxicities.

Material and Methods

81 curatively treatable patients with intrathoracical

carcinoma (NSCLC, SCLC, esophageal carcinoma) were

included in this analysis. They received radio-(chemo-)

therapy. Patients with NSCLC were treated with 74 Gy,

patients with SCLC with 60 Gy and those with esophageal

carcinomas with 66 Gy. Eligible patients received
