Abstract
Background: Head and neck cancers account for 2 to 5% of body cancers and 
radiotherapy is one of the treatments for these conditions. Destroying cancer cells 
without damaging healthy cells around the tumor is very difficult. Cancer cells 
eventually die after repeated injuries by radiation in various treatment sessions, but 
unlike cancer cells, repair and replacement of normal cells happens between 
treatment sessions. In these patients, the most important complications are skin and 
blood complications. The occurrence of these complications may cause interruption 
of treatment by physicians’ order or patients’ request. Discontinuation of treatment 
may result in disturbance of tumor cells destruction that is the main purpose of 
radiotherapy. The high prevalence of head and neck cancer that are candidate for 
radiotherapy, and the increase use of electron beam therapy have made the 
occurrence of acute skin reactions and reduction of blood factors inevitable. In this 
cross-sectional study, we evaluated 60 patients include 22 female and 38 male 
patients who underwent neck and head radiotherapy from March 2017 to March 
2018 in Sanandaj, west of Iran. For this purpose, by assessing the weekly blood 
tests, we evaluated blood cells changes. The rate and intensity of acute skin 
complications were recorded according to the RTOG ( radiation therapy oncology 
group) scoring system. Then, the collected data were entered into SPSS version 20 
and ANOVA test was used for analysis. P-value<0.05 was considered statistically 
significant. Results: The evaluation of 60 patients' tests revealed that blood factor 
changes happen during radiotherapy. Mitotic catastrophes occur in blood cells and 
bone marrow suppression happens concurrently and without replacement. Regarding 
the radiation-induced skin complication, there is not a notable complication in the 
first weeks (first and second weeks), but from the late third week, these 
complications begin to manifest and continue to the tenth week, then the intensity 
mitigate and acute complications recover and became mild. In this study, the 
intensity of complications depends on the total and fractional delivery schedule 
doses. Conclusion: skin complications and blood factor changes occur during 
radiotherapy frequently. The changes of different blood factors are not the same and 
some of them can undergo decrease whereas increment happens in others.

1 BACKGROUND:

Head and neck cancer account for 2 to 5 per-
cent of all body cancers and include cancers
in the upper gastrointestinal (GI) and respi-

ratory system. For example, paranasal sinuses, nasal
and oral cavity, oropharynx, hypopharynx, larynx,
and upper esophagus. Radiotherapy is an integral
part of therapy for cancer patients that is used alone
or in combination with other therapies like surgery
or chemotherapy. Half of the cancer patients, ex-
perience radiotherapy as a part of their treatment.
The effect of radiation on normal cells causes the
complications of radiotherapy. [1] Cancerous and
normal cells react differently to radiation, but erad-
icating cancerous cells without damaging normal
cells around the tumor is very difficult. The damages
of repeated radiation would kill the cancerous cells
eventually but recovery and replacement of normal
cells, unlike cancerous cells; occur between thera-
peutic sessions.[2] Although cancer patients do not
feel any of these intracellular changes, the radiation
effects on cancerous and normal cells would in-
crease gradually that can even cause cessation of the
treatment.[3] The intensity of the skin complications
correlates with different factors like total radiation
dose, technique, and place, the volume of irradiated
tissue, chemotherapy, chronic disease, dose param-
eters, time, and fractional doses.[4] Different scor-
ing systems are used for determining the extent of
radiation-induced skin complications (RISC). Scor-
ing skin complications according to clinical manifes-
tation and patient’s expression is classified into 4-
5 grades. These complications vary from mild ery-
thema to dry desquamation and moist desquamation.
[5] The high prevalence of head and neck cancer
candidates for radiotherapy, and using low depth
electrons are inevitable reasons for acute skin com-
plications. The occurrence of these complications
may persuade physicians or patients to cease the
treatment. The cessation of treatment may disturb the
destruction of the tumor that is the main purpose of
radiotherapy. [6]
Bonemarrow cells are the main hematogenous tissue
in the body are the most sensitive tissue against ra-
diation. Pelvis and vertebra bones account for about
60% of blood-producing tissues, and ribs, skull,

sternum, scapula, proximal femur, and humerus
bone account for the 40% remaining. Damaging the
hematogenous tissues reduces blood cells number
and changes the hemoglobin and hematocrit. [7]Dif-
ferent blood cells have a different sensitivity to ra-
diation, and the first lymphopenia, then granulope-
nia, thrombocytopenia, and anemia lastly occur. The
extent of damages depends on different factors like
the amount of received radiation, radiation time, the
number of sessions, and the volume of irradiated
tissue. [8] The level of hemoglobin and white blood
cells can affect the response to radiotherapy, radio-
therapy in patients with a high level of hemoglobin
and hematocrits is more effective in comparison to
patients with anemia. [9]
The high prevalence of acute skin complications
and utilizing low depth electrons, reduction of blood
cells and RISC is inevitable that cause cessation of
treatment. This cessation may disturb the eradicating
of the tumor that is the main purpose of radiotherapy.
[2] Given the acute skin complications and reduction
of blood cells caused by radiotherapy that affect the
treatment and patient’s quality of life, the present
study aimed at evaluating the frequency and relation-
ship between these complications among head and
neck cancer patients.

2 METHODS:

in this cross-sectional study, 67 patients include 42
male and 25 female patients were study from March
2017 to March 2018. This study was conducted on
patients who underwent radiotherapy on the head and
neck. For this purpose, by evaluating the patients’
blood test, blood cell changes were identified. For
each patient, the blood cell test was performed and
recorded in the patients’ files during therapy. The

extent and intensity of the acute skin complications
were scored according to the RTOG system. This
evaluation started from the first day and up to the
thirteenth week of treatment. Finally, after analyzing
the data, the frequency and intensity of complications
were evaluated. For evaluating blood cell changes,
blood cell counting was performed before, during,
and up to the end of radiotherapy using formula. In
this evaluation, in addition to red blood cells (RBC),
white blood cell (WBC), platelet, and hemoglobin,
partial and complete lymphocytes and neutrophils
were evaluated too. This evaluation was performed
for all the weekly tests. Other information like demo-
graphic information, cancer type, treatment type and
place, dose, the number of sessions, and duration of
treatment were recorded. Finally, the SPSS version
20 was used for analyzing obtained data; an indepen-
dent t-test was used for analyzing descriptive data.
P-value<0.5 was considered statistically significant.
Ethical consideration :
The study protocol was approved and funded by
Kurdistan University ofMedical Science.Written in-
formed consent for participation was obtained from
each participant after full disclosure of the aim of the
study.

3 RESULTS:

out of 67 eligible patients, four male patients (Iraqi
patients) and three female patients (death during the
study) were excluded from the study and 60 cases
(38 male and 22 female) remained. The patients’
ages range from 24 to 85 years with a median of 57
years. Treatment period range from 29 to 64 days.
The cumulative dose varies from 31.9 to 75.2 Gy
(Table 1).
Regarding the cancer type, 46 cases of carcinoma, 4
cases of sarcoma, and 10 cases of lymphoma com-
prise the patients. Out of this number, 25 patients
underwent surgery, and 35 cases did not undergo
surgery. Also, 13 patients received chemotherapy be-
fore radiotherapy, 47 patients did not receive it, and
31 patients received radiotherapy and chemother-
apy concurrently. Radiotherapy type was on fraction
schedule and the daily doses were 180, 180-200,

and 200 cGy for 30,20, and 10 cases respectively.
The skin complications were evaluated according to
the RTOG system weekly for 13 weeks (table 2).
Most of the skin complications in these patients were
observed in grades two and three (figure 1, table2).
Patients’ blood cells including leukocytes, erythro-
cytes, platelets, neutrophils, and lymphocytes before
and after treatment were measured based on the
Pearson correlation coefficient. According to this
analysis, there was a significant relationship between
these blood factor changes and radiotherapy (table3).
In the first week, the number of white blood cells
decreased, which stimulated the bone marrow, and
in the second week, the number of lymphocytes
increased, but in the third and fourth weeks, it de-
creased due to bone marrow intense suppression
(figure 2). The rate of decrease in red blood cells
during treatment was gradual (figure 3). The platelet
size was constant in the first and second weeks
and decreased in the third and fourth weeks due
to platelet loss after mitotic death due to radiation
(figure 4). Neutrophils increased during irradiation
(figure5).
Lymphocytes decreased between the first and second
week and remain constant in the third week, and
decreased again in the last week (figure 6).

4 DISCUSSION:

One of the common therapies for head and neck
cancers is radiotherapy. In this method, a radiation
source (internal or external) is used for irradiation of
the tumor-bearing tissues. In radiotherapy, especially
the external one, in addition to tumor, the normal
cells around the tumor-bearing tissue are irradiated
too. Radiation would damage the cells that eventu-
ally kill them. The more multipliable, the more sen-
sitive to radiation. [8] Radiation would affect bone
marrow that is the hematogenous tissue in the body.
Blood cells have different sensitivity to radiation
in a way that first lymphocyte, then granulocytes,
thrombocytes, and lastly anemia occurs. The cumu-
lative dose, the number of sessions, the dose, and
the volume of irradiated tissue are among the factors
that influence the blood cell changes.[7] In a study

entitled theI impact of white blood cell count and 
hemoglobin level on the response to radiotherapy in 
patients with colorectal cancer “, chiao and col-
leagues revealed that patients with a high level of 
WBC and hemoglobin respond better to radiother-
apy.[9] In line with our study, Faraji and colleagues 
reported that the decline of WBC correlates with the 
cumulative dose of radiation, and the decline of 
hemoglobin and platelet correlates with the length 
of the radiation period.[10] The intensity of skin 
reactions depend on factors like radiation type, ther-
apeutic technique, irradiated tissue position, dose, 
and period length. According to clinical manifesta-
tion and patient’s description, radiation-induced skin 
reactions are classified into 4 to 5 grades. These 
complications vary from mild dry desquamation to 
moist desquamation[5] that may persuade the physi-
cian or patient to cease the treatment, and disturb 
the purposeful therapy.[6] The result of a study con-
ducted by Yungjing Wang on 47 anaplastic thyroid 
carcinoma patients in 2002 revealed that patients 
who received higher fractional dose manifest acute 
dermatitis grade III whilst patients who received 
palliative care and lower dose did not manifest der-
matitis that is in line with our report.[11] The result 
of another study by Tejpal and colleagues on 264 
patients inflicted with advanced squamous cell carci-
noma of the head and neck that treated with cisplatin 
and radiotherapy (CRT) concurrently showed that 
the mean age was 54 years, and dermatitis grade III 
(RTOG-3) occurred in 35 percent of patients.[12] In 
a systemic review by Langendijk and colleagues on 
the efficacy of radiotherapy and Cetuximab (CRT) 
on head and neck squamous cell carcinoma patients 
revealed that skin reactions correlate with radiation 
dose and therapeutic technique, and response-dose 
relationship applied for the occurrence of RISC.[13] 
In this report, we concluded that blood cells undergo 
changes during therapy. During radiation, the WBC 
would reduce at the first week that triggers bone 
marrow that causes lymphocytosis at the second 
week, but at the third and fourth weeks of radiation, 
due to suppression of bone marrow, a large reduction 
of lymphocyte would occur. Regarding RBC, there 
was a gradual reduction in its number that can be 
explained by the longer lifespan of a red blood cell. 
The size of the platelet remained unchanged during

the first and second weeks, but from the third and
fourth weeks, it would decline that is due to the
destruction of platelets and mitosis death due to radi-
ation. Radiation has a different effect on neutrophils,
and a growing trend was observed during therapy.
Regarding RISR, no notable complication was noted
at the first and second weeks, but gradually from the
late third week, the skin complications would start to
manifest as dry desquamation and sweat reduction.
This trend would continue until the tenth week. The
intensity of reactions varies from a mild reaction
to moist desquamation and generalized moderate
edema, and even wound, bleeding, and necrosis was
observed in four patients. From the tenth week on,
the intensity of complications decreased, and the
acute ones recovered and became mild. In this study,
the intensity of complications correlates with the
cumulative and fractional scheduled doses.
It worthmentioning that for preventing these compli-
cations during radiotherapy, from the first week until
the thirteen weeks we evaluate the skin complica-
tions and refer patients to dermatologist weekly. Ar-
ranging these appointments made some difficulties,
especially for patients from other cities that made us
exclude foreign patients.
The limitation of our study was the low number
of participants. It is recommended to perform this
study on a larger number of patients to obtain more
accurate results.

5 CONCLUSION:

Skin complications and blood factor changes are the
most frequent complications of radiotherapy. Our
study revealed the different blood factor changes and
its relationship with the stage of the radiotherapy.
