Introduction
Pancreatic ductal adenocarcinoma is one of the most common
malignant diseases of the pancreas having its origin in the ductal
epithelium. It is considered a malignancy with a high degree of lethality,
survival at 5 years being reported to be up to 4%. Tis poor outcome is
due to both a low specifcity of onset symptoms (e.g. the disease is usually
diagnosed in advanced stages) and also to a lack of tumour markers in
order detects the presence of the tumour in the early stage, as well as the
absence of efective non-surgical treatment modalities [1-3].
Up to now surgery is the only treatment modality that can provide a
greater chance of survival, but unfortunately is an option only for about
15% of patients. In this way, early pancreatic surgical experiences were
accompanied by increased morbidity and mortality [4,5].
In fact, in the in the 1960 and 1970 few pancreaticoduodenectomies
were made, considering that hospital mortality was high (e.g. around
25%). However, throughout the 1980s and 1990 the experience in
performing duodenopancreatectomies grew and specialized centres in
pancreatic resections have emerged, with the postoperative mortality
and morbidity decreasing down to 3% [6].
In this way, the surgical resections are representing to this date the
only chance for curative care. Te presence of hepatic or peritoneal
metastases or the appearance of a tumour invasion of the celiac trunk
or superior mesenteric artery have been widely accepted as absolute
contraindications for resections, but despite these selection criteria,
the median survival and survival rates at 1 year have been reported
to be between 15-17 months and respectively 55-68%, even afer the
macroscopic curative resection [7].
In addition, a major disadvantage of this disease is the fact that the
diagnosis is still late, despite the development of new technologies. In
this way, the main symptoms (e.g. pain and jaundice) are occurring
later on, when the tumour is already locally advanced and unresectable.
Tus, for now, the only hope to establish an early diagnosis, potentially
curable, is represented by a rigorous anamnesis for the early symptoms
that will send the patients to the doctor in an early stage.

Abstract
Pancreatic ductal adenocarcinoma is one of the most common malignant disease of the pancreas having its origin
in the ductal epithelium. With an increasing incidence, it is considered one of the most aggressive human tumours. It
has a high degree of lethality, survival at 5 years being reported to be up to 4%. This poor outcome is due to both a low
specifcity of onset symptoms (e.g. the disease is usually diagnosed in advanced stages) and also to a lack of tumour
markers in order detects the presence of the tumour in the early stage, as well as the absence of effective non-surgical
treatment modalities. Up to now, surgery is the only treatment modality that can provide a greater chance of survival,
but unfortunately is an option only for about 15% of patients. The resections for the pancreatic cancer have entered the
therapeutic arsenal for almost 70 years, but despite hundreds of reports written about this topic, there is no unanimity on
the effectiveness of the resection. In this way, we will describe here some current aspects and survival numbers related
to resectability in the pancreatic cancer.

Actuarial Versus Actual – Relevance for the Interpretation
of Existing Statistical Data
Te resections for the pancreatic cancer have entered the
therapeutic arsenal for almost 70 years, but despite hundreds of reports
written about this topic, there is no unanimity on the efectiveness of
the resection. In this way, several authors have reported a survival rate
of 30% or even 58% at 5 years [8,9]. Tere are even authors reporting a
100% rate [10].
On the other hand, Gudjonsson et al., states that in reality we
documented only 1200 cases from roughly 200,000 patients reported
since the beginning of the resections. In addition, a source of error
consists in the fact that some survivors at 5 years were reported several
times: same period of survival corresponding of some patients from
an institution was reported up to ten times. Tus, some published
articles report data collected from several institutions, each of the
having already reported the data in the prior period. For example,
one patient was reported in two diferent countries, 6 times in total.
Moreover, the cases without resections and with survival at 5 years have
been published in 18 reports from 6 diferent countries, thereby they
are well documented. In this way, afer correcting the repetition, the
survival group at 5 years afer resection was represented in reality by
only 350 patients corresponding to a period of 65 years carrying out the
pancreatic resections [11].
Te data about survival are published as actual and actuarial
survival. Tus, several working groups report their experience regarding
